1. "Czechoslovakia was the chief industrial center of the former Aurcro-aungarlan
Monarchy. .The important development of industry in this country has the origin
in its mining, which is of very ancient date. Iron ore was already being mined
in the 7th century; later came gold, silver and lead, mined from as early as the
13th century. As early as the 16th century brown coal was being mined and in
the 17th century mining of pit-coal began near Pilsen and Kladno. The pit-coal
in the Ostrava was discovered in the second half of the 18th century and its coal
output was able to increase comparatively rapidly, because the steelworks of
Vitkovice, which consumed large quantities of Ostrava coal, and later large
quantities of coke, were already founded in 1829.
The second large steelworks in Trinec were founded a few years later and these
works also consume large quantities of Ostrava coal and coke.
Therefore Czechoslovakian industry has an ancient tradition and in many branches
is world-famous for the quality of its products. The coal, coke, and steel
greatly participated in Czechoslovakian industrial output and export.
The following figures show the participation of different products in Csechos
lovakian exports for the year 1929.

Coal and coke are the most important articles in export of raw and semi-manu-
factured products such as steel products, and in the export of finished industrial
goods.
2. 'The principal pit-coal basins in Czechoslovakia are as follows:
(a)
The Ostrava-Karvina coal-field is situated at the eastern boundary
of Moravia and Silesia and constitutes the southwest part of the upper-
Silesian coal basin. The coal here is of an ancient foundation) its
mining is difficult, but it gives coke of excellent quality.
This coke is supplied to the largest Czechoslovakian steelworks in
Vitkovice and in Trinec0 is sent to the west for the supply of the Skoda
Works, and to the east for the supply of the Podbrezova State Works.
(b) The Kladav-Slany-Rakovnic district, extends 20 kilometers northwest from
Prague. The coal of this district was unsuitable for coke production
but now, in mixture with the coal of the Ostrava district, it ii used
for production of metallurgical coke for the steelworks in Kieft�, in
Kraluv Dvur, and in the new coke-oven plant built in Kladno.
(c)
The Pilsen-Radnice district supplies pit coal to another important
industrial center in Czechoslovakia, Pilsen, with the famous Skoda works
and large Kaolin and fire clay-industry. This district doesn't produce
coke.
(d) The Rosice district near Brno in Moravia has its own little coke oven
plant and it supplies metallurgical coke to many grey-iron foundries in
Brno and its suburbs.
(e) The Svatonovice district in northeast Bohemia doesn't produce metallurgical
coke but supplies coal to the local textile and paper industries.
(f)
In the Budejovice district are occurrences of anthracite, used mainly to
meet the demand of this district.
The pit coal and coke production in the Czechoslovakian Republic in 1929 was as
follows:

"In addition to the pit-coal production, Czechoslovakia is one of the
producers of brown coal in the world.
The brown coal output in 1929 was as

Czechoslovakia has a big disadvantage in being a large distance from the sea.
On the other hand, this country has an important advantage, in that the centers
of brown and pit-coal are located equally within the whole republic, and the
expenses of coal transportation are not so severe.
Ostrava Karvina Coal District

companies in the Ostravo-Karvina district. The number of mines and of coke
oven plants, and the total output of each company in 1929 are presented in the

Table 5 with the figures for
every mine is given on following pages.
With the exception of a few anthracite seams with 10 to 14 percent of volatile matterj
the southwest part of occurrence (in Ostrava and in the near neighborhood) give an
excellent fat coking coal with 15 to 25 percent of volatile matter. This coke is
especially excellent for the foundry and cupolas and is produced in the coke oven
plants of Ignat and Frantishek.
In the eastern direction the amount of gaseous matter increases so that in front of
the Orlova fault, (which divides the district into the eastern and western parts),
the pits of Petwald in the eastern part contain a gas coal with 36 to 42 percent
of volatile matter. On the other side of the Orlova fault, there are seams of
relatively good coking coal with 30 to 32 percent of volatile matter.

The cOke from this part of the district is very popular, primarily as coke for
heating.
*The coke originatingfrom the gaseous coal of the eastern district is excellent for
blast fUrnaceS. The coal from this part of the occurrence is delivered to the
coke-oven plants in steel plants in Yitkovice and in Trinec and is also transformed
into metallurgical coke in the coke oven plants belonging to the pits. The coke
from them is delivered to the blast furnaces at Podbretova, Kraluv DNur, Kladno
and is also exported. The excellent quality of this coke for the blast furnaces
consists in its compressive strength and also its good porosity. Also a little
content of phosphorus in the ashes of this coke helps in the production from blast
furnaces of pig iron of the best quality.
To give an idea of the quality of coal the following characteristic chemical analyses
are given;

6. "On account of the excellent coking properties of the Ostrava-Karvina coal, Vgaxioke
Made from it was used at the very commencement of the iron and steel industry in this
district.
The first ovens were installed in the fifties of the last century at the Anselm pit
and the Ida pit in western part of the district. Since this beginning the capacity
of the ovens and its output constantly increases.

The number of ovens was again decreased some more, because.all old ovens erect71xefore
the year 1910 were stopped and replaced bY new ovens, which gave the same prod on
with less number of ovens, The following items on the above table were stopped: 1, 2,
5, 6, 7, 11, 20, 25, and 28. Between the new construction, there are the ovens built
in Kladno in Bohemia and in Hohenegger (Batlore) in Karvina., For the foreseeable
increase of iron and steel production according to the .ve-year plan, the actual
number of ovens is not sufficient, and new ovens must be erected,
8. 'Opposite to the former tendency to build the ovens near the pits, the new trend is the
erection of new ovens in the iron and steel plants, in which the coke oven gas can be
better utilized and the ovens alone can be heated by blast furnace gas, which is cheaper
for its leafs calorific value, On the other hand the transportation of coke is more
simple and the qnality of coke by itself doesn't suffer during the transportation, the
crushing of coke is prevented, and the run of the blast furnaces is better.
According to the five-year plan the new ovens at first were built in the Kuntchice,
near Ostrava, where is located the new iron and steel plant, belonging to the VitkoVice
iron and steel works, Later, the equipment and a group of skilled bricklayers had to
go to Poland and after they return, this group may build the new ovens in Trinec.
Also the new iron and steel works in Tuscansvy St Martin will include the new coke
oven plant, supplied by the coal from Karvinna.
It is necessary to add that the wells of natural gas are discovered near Teshin and
the supplyof this gas for heating the open hearth furnaces in Trinec is foreseen.
On the other hand the coke oven gas produced in the coke oven plants: Ignat, Frantishek�
Knrolina and Trojice is supplied by fat gas piped, to the Vitkovice Iron and Steel Works
and to Bohumin, and this gas will supply the industrial plants in Rabrek� Kbprionice,
Prostejov and Olomouc.
The excellent qualities of coke produced in the Ostravs. Karvins district have been
well known abroad and for many years the Ostrava coke had round its market especially
in Poland, Austria, Hungary, Italy and in the Balkans. Some of the exports tc these
countries is conserved now,
"But relative to Poland, a new way has been found, In 1948 there was concluded an
industrial agreement between Czechoslovakia and Poland, According to this agreement
Czechoslovakia began to export not coke but coking coal for production of coke in
Poland itself.
The reasons for this agreement between Czechoslovakia and Poland are as follows:
Czechoslovakia was not only the chief industrial center of the former Austro-Hungarian
Monarchy, but was also the chief center for the industrial export frou this State, The
industrial export from Czechoslovakia increased after the first World War, because all
other parts of Austro-Hungarian Monarchy were found to be abroad. The quality of
Czechoslovak industrial goods and the skill and the individual experience of
Czechoslovakian people are world-known.
On the contrary Poland is mainly an agriculture country and its industrial developed
parts are only the region about Ludz (textile industry) and the regions obtained from
Germany. The skill and experience of Polish industrial people are less developed than
the Czechoslovakians, Poland inherited from Germany the rich pit coal basin of Upper-
Silesia and was found to be the main exporter of pit-coal in Europe, After the second
World War this heritage was increased again because Poland also received the part of
this district, which after the first World War still remained in Germany.
Czechoslovakia owned a part of this basin too, (it is OstravnZarvina district) but
it is only the edge of stratum, the geological structure of which is quite different
than the Polish one. In Poland the seams of pit coal are horizontal and its thickness
is of value of many meters. In Czechoslovakia the thickness of coal measures decreased
somewhere to one half meter and the slope of seams reach 900. It is obvious the
mining of pit coal in Czechoslovakia requires more manpower and is more expensive than
in Poland. The output of the pit coal industry in Czechoslovakia is not sufficient to
cover all needs of this country,

Instead in 1929 Czechoslovakia exported:
1,8540285 metric tons of pit-coal
3,069,604 metric tons of brown coal
and at the same time imported:
20330,649 metric tons of pit-coal
107,226 metric tons of brown coal
The final balance was as follows:
50X1
Import: 2,330,649 - 4854,285 m 4760364 metric tons of pit coal
Export: 3,069,604 - 107,226 m 2,962,378 metric tons of brown coal
The results show Czechoslovakia actually exported only brown coal, but imported more
of the pit coal than it exported. The main part of imported pit coal is the pit
coal from Poland, This import was directed to the regions where the price or Polish
coal, including the cost of transportation, is less than the price of Ostravian coal
including the cost of its transportation. These are the north-eastern regions of
Bohemia. In addition, the Polish coal is excellent for the production of the producers
gas, because it sinters very little.
After the world crisis the import of Polish coal decreased because the need for coal
fell in the country, but during the extensive output of whole Czechoslovakian industry
within and after the last war, the import of Polish coal increased again.
10. " In order to decrease the price of the Ostravian coal in its competition with the
Polish coal, the Ostravian mining corporations made extensive mechanization of mining
in its pits, In this field, the Ostrava district has one of the best equipped in
Europe. In 1929, 8303% of whole output was mined by mechanical means. .In the course
of eight years from 1921 to 1929, the productivity of one miner was doubled from 1450
to 2910 tons, After 1929 the mechanization in Ostrava district was to be more advanced.
After the second World War the need for pit coal increased again. The raising of the
output of the mines by mechanical means is difficult, This raising can happen only
by the increase of manpower occupied in the pits, In fact, the opposite happened;
among the miners one-third of them were Germans and after the war all miners of
German origin were sent to Germany. The success of the five-year plan mainly depends
on the increase of the output of pit-coal mines. The solution was to be found in
the conclusion of Polish-Czechoslovak industrial agreeMent,
11. "Poland promised to export to Czechoslovakia the lacked quantity of pit coal. Poland
easily gave this promise because her export of coal to other countries waa cut during
the "cold war",
On the other hand Poland needs good coke for her blast furnaces, and coke produced
in Polish coke oven plants hasn't sufficient quality for a good run of Polish blast
furnaces. Besides, the increase of iron and steel production according to the Polish
six-year plan also requires the raising of production of coke and the capacity of
Polish coke oven plant is not sufficient as of now. Poland needs to import the coke
from Ostrava-. Kervina basin.
But the output of Czech pit coal mines is not sufficient for Czechoslovakia herself.
Also production of coke in Czech coke oven plants requires the 100% supply of Czech
coal, The solution was to be found. in the export of Inrvina gas coal to Polish coke
oven plants, because the quantity of exported coal is less than the production of coke
in Czech coke oven plants.. Poland merely adds this coal to the mixture of their own
coal and improves the quality of produced coke in their own coke oven plants.
This solution is very simple. Why wasn't this solution found long before? The
explanation is as follows. The policy of Ostravian mining corporations 1143 not to
provide the export of coking coal for the production of coke abroad, but to press
on the foreign customers to order the coke in Czech coke oven pleats. The sale of
coke was more psefitable than the sale of coal, because besides tbe profit from sale

of coal, the mining corporation received without charge the coke oven gas and the
other by-products which could also be sold. The concluded agreement signified a
reversal of the traditional Czech Policy of not selling the coking coal from Ostrava
basin and helping in the solution of the old quarrel between the Czech and Polish
people about the Jeshin and the Karvina regions, Because the Polish coke oven plants
are old and its output doesn't satisfy the grown consumption of coke in the Polish iron
and steel industry, the Czech government sends its group of skilled bricklayers to
build the new coke ovens in the Polish iron and steel works.
4In order to compare how the quality of Polish metallurgical coke improves after an
addition of Czech coking coal, the Table 11 following gives the figures about the
technical indices of Polish coke oven plants before and after the conclusion of Czech-
Polish agreement.

In 1948 the addition Wasn't executed but in 1949 it was. (1949 results show addition
of Czech coking coal)_.
This table shows that the coke oven plant "Florian" is the only one in Poland which
has modern equipment. The equipment of the other four plants is very old and the
same equipment in Czechoslovakia was dismantled a long time before the second war.
Especially is this so at the coke oven plant "Pouoj", which has a small output and the
bad quality of coke produced. After the agdition of Czech coking coal, the output of
this coke oven plant raised from 348 of /mJ of volume of furnace at 24 hours to 430
of /m3 of furnace at 24 hours, and the raising of output is almost 24% but the quality
of coke was not improved.
13. �To make up for it, the quality of coke for blast furnaces greatly improved in the three
other plants. The fifth coke oven plant "Zygmunt" produces coke only for foundries.
On average the amount of ash in the Polish metallurgical coke decreased i%, the drum
test improved 6.24 and the amount of dust after this test dropped 11%.
This better quality of metallurgical coke improved the run of Polish blast furnaces
in spite of the added burden imposed on the furnaces.
The next table (12) gives the figures showing this improvement of run of Polish blast
furnaces.
