The method is based on the following geological, pros- pecting and analytical data: 1) ore-bearing capacity of rocks in the ctors which govern Krivoy Rog.metamorphic series and geological fa mineralization (structural, stratigraphic, lithologicall metamorpho- enic, hypergenic); 2) form, dimensions and quality of the ore g eposits and their'change with depth; 35 complexity of the morphol- ogy of ore.,deposits and the expoeure of,ore-deposit profiles which...

As a result of these studies, a new classification of ore deposits in the Saksagan belt, based on natur-i~ al factors, was developed for prospecting purposes. An optimum pros-,- pecting-network density has been established for each group of depo sits. This density is considerably lower than both the currently employed density and that recomended by the rK3 (GKZ) but ensure -satisfactory accuracy of determination of reserves and reliable des cription of their quality (cf. table). An increase in the reserves of rich ores is to be expected mainly at large depths. Because of this, and also in view of the desirability of reconstruction of mines, it is necessary-to solve the following main problems of de- tailed prospecting: 1) constant replacement in the process exhaust- ion of class B reserves in order to ensure a regular planned develop- ment of major deep-mining operations; 2) sufficient geological Card 2/5 S/169/63/000/001/041/062 A method of detailed D218/D307 studies of 1000-1500 m horizons, ensuring rational distribution of capital investiment in reconstruction and sinking of new mines. A rsion existing working depths, prospecting operations aimed at conve of the reserves to class B, can best be carried out from wells sunk from newly prepared or exhausted mining horizons. The well depth will then be less than 250-300 m. It is possible that a proportion;,.. uf the wells will best be sunk from the surface. In order to decide.' n -.-:.1-,on the optimum conditions, special preliminary analysis of the eco mical, time and technological factors is necessary. The followingi data should be determined.in deep-horizon studies (1000-1500 m): the presence of ore-deposits should be confirmed, a preliminary es- timate should be made of the size and quality of the mineralizationll the form and deposit elements of ores, and the details of the gener-_t.l~ al geological structure. It ts also desirable to have even prelim- .-.3.nary estimates of hydrogeological and mining-technological working conditions. For Krivoy Ro deposits, this degree of exploration s.

TITLE: Scientific foundations of rationalized prospecting for iron deposits of Krivoy Rog PERIODICAL: Referativnyy zhurnal, Geofizilta', no. 1, 1963 11-12 abstract 1D58 (Geologichniy zh., 1962, v. 22: 14-29 Mr.: summary in Rusj)) TM(T: In order to ensure the borrect development of geolog. ical prospecting-operations in the Krivoy Rog basin, it is necessary to take into account lithological-stratigraphic,,~tructuralI meta- morphic, hydrogeological, and geomorphological factors governing the mineralization. The development of a rationalized method for detail,-- ed prospecting for rich ore deposits in the Saksaganskiy and Ingulet skiy ore fields is largely determined by the dimensions and the structural complexity of ore-bodies in the central Krivoy Rog depos- its, e.g. variability in the occurrence'of'-f-erivginous quartzites?.", and the complexity of,,the geological and'internal'structure. In Card 1/3 S/169/63/000/001/042/062 _Scientific foundations ... D218/0307 choosing the rationalized method of detailed prospecting, the author,' suggests the use of a new classification of deposits which was devel6-"._1,-'_ oped with allowance for the main factors which characterize the prosk. pecting procedure. Currently used prospecting-network density is 1-- considerably louer than that recommended by rK3 (GKZ), but is overt.; estimated by a factor of about 2 for the major ore rich deposits in the Saksaganskiy and Inguletskiy fialds which belong to group 1. Average-size deposits of this type, which belong to the second gro UP and also deposits in the central Krivoy Rog field, are at present being investigated with a network whose density is nearly optimal, and it is recommended that this density be retained. Ferruginous quartzite deposits belonging to the first subgroup (deposits with simple internal structure), which belong to all the prospecting t. . ... groups, are being investigated with a network density which is near- -ly optimal. The second subgroup of all groups (deposits which have complex internal structure) are being investigated with insufficient,' well-network density. In order to determine the extent of the oxi- dation zone of these deposits with depth, the prospecting-network density should be higher by a factor of roughly 4. The prospecting- C ard 2/3 sA691631000100110421062 Scientif ic foundations. 4. 0 D218/0307 network density should not be chosen for individual deposits but for the ore site as a whole. The density of prospecting wells should ensure normal exploration of most of the rqserves. The degree of exploration of rich ores should be estimated not from the reserve categories but-from prospecting data which.olight to be obtained prior to the mining data. The degree of exploration of rich ores should be regarded as normal when most of the reserves at 280-320 m below the working horizon can be described-As class B. At the maxi- mum depth of mine reconstruction (1200-150Q_m) most of the reserves should belong to class Cl. In-order to reduce Class 0 deposits to Class B, it is generally expedient to work-through exibting mine pits.

Transverse Flow (Aerodinainicheskoye soprotivleniye poperechno, obtekayomykh trubraykh puchkov, obladayushchikh svoy3tvom samoobd-avki) PERIODICAL: Teploenergetika, 1958751ir 81 pp 48-51 (USSR) ABSTRAMThe efficiency of boilers is much affected by the formation of deposits on the heating surfaces. Investigations carried out at the All-Union Thermo-Technical Institute (Teploenergetika Nr 1, 19,54) are so far 'Ghe only ones that make a systematic study of tho process of deposit for- ination: they show that contamination can bo minimised by reducing the tube din-meter to 25 - 30 ium and using honeycomb arrangenents with short lon.-itudinal tube pitch. Labes in honeycomb arrangement are less subject to deposit formation than those in square fornition and if the pitch values are suitably choser. they are self-cleaning. T h i S arrangement is reconL-nended for ind:astrial use, particularly bard 1/4 in boilers. However, little o.-r-perimental data is available on the acrodynaudc resistance of tube bundles in So 58- 8 -31-0122 The Aero-Dynanic Resistance of Self- cleaning Tube Bundles with Transverse Flow honeycomb arrangement and the present work was undertia1ten to fill the gap. The inve stigat ions were quarried out on L 6-row bundles of tubes, the geomotrical characte--ristics of which are given in Table 1. The tests, were na-de with isothermal flow of -air in an open-type urind tunnel of section 250 x 250 mm at Reynolds numbers ranging from 21500 - 20)000. The resistane of the tubes .was deter- mined from the static pressure-difforenca before and after the bundles. The experimental equi Pment and p.o,_edu.e are described in Teploenergetilca Nr Ii-I The test results are plotted in lo-aritlwAa co-)rdinates in Fig 1. The resistance of the bundles is given as a, function of the lon-,itudinal and transverse ',Ube pitahes. An equation relates the criteria of similarity for the bundles investi- gated, and values of the constants entering into the equation are given in Table 2. The results show how the Card 2/4 resistance of the bundl(s depends on the pitches; as the transverse pitch is increased, the influence of the SOV/96-58--8-10/22 The Aero-Dyrwmic Resistance of Self-cleaning Tube Bundles with Transverse Flow longitudinal pitch becomes less. When the arrangement of the tubes is such that the rates of flow over them in the longitudinal and diagonal directions are equal, the aerodynamic resistance is particularly loii. The advan'Gages are specially marked when the transverse itch is small, as will be seen from the graphs in D ig 2.

(Engineer) TITLE: An Investigation of Radiant Heat Exchange in the Furnace of a Boiler when Burning Natural Gas PERIODICAL: Teploenergetikaq 1959, Nr 10, PP 31+-38 (USSR) ABSTRACT: Heat exchange in boilers is mostly by radiation. The standard thermal design procedure for boilers developed by the Central Boiler Turbine Institute is an empirical method that gives satisfactory results within the limits of the experimental material on which it is based. However, the opinion has been expressed that the standard procedure does not give sufficiently accurate result3 in furnaces burning natural gas. Therefore, in making balancing tests on a small boiler burning natural gas the authors simultaneously Investigated radiant h,~at exchange A diagrammatic cross-section of the boiler indicating the .Location of measuring instruments is given in Fig 1. The Card boiler had previously burned solid fuel. The boiler has 1/4 a steam output of fourteen tons per hour, a furnace volume of 26 m3, ana a radiation surface of 20.5 m2; the sov/96-59-lo-6/22 kr. Investigation of Radiant Heat Exchange in the Parnaee of a Bofl.cr when Burning Natural Gas -total surface of the furnace walls is 62.3 m2 and the degree of sereening 0.33. Two gas burnors of the t~rpe sketc.hed In Fig 2 were installed in the front of the .furnaca. The extent to whioh the most; Important con- ditions were maintained comstant during the tests will be seen from Fig 3. Natu:ral gas from the Shebalinslwye field was used; its analysis is given and its calorific value is 9050 knal/m3 at n.t.p. The measurement procedures used are described. Gas temperature curves at the outlet from the fu7naae when operating with an excess-air factor of 1.11 are plotted in Fig )+. The temperature is seen to be very high near the back wall of the furnac:e, mainly beoause the screening factor is so low. The fiame temperature is evidently 1600-1650 ()C, whieh can damage the furnace lining. With normal excess-air factors the flame is short and fairly transparent-,; with low excess- air factors it becomes violet. The resultsof radiant hea, Card e-Kchange calculations are tabulated, and it will be seen that the excess-air factor ranged from 0.91 to 1.61~ The apparent thermal loading of the furnace -volume ranged froz L 2.96 x 1o3 to 445 x lo3 kcal/m3hr. The tabulated data sov/96-59-lo-6/22 An Investigation of Radiant Heat Exchange in the Furnace of a Boiler when Burning Natural gas was used to calculate the direct heat output as a functior of loading and as a function of the excess-air factor; the curves,obtained are plotted in Figs 5 and 6 respecti- vely. The dotted curves in Fig 6 relate to the detailed study of radiant heat exchange in a gas furnace of a boiler of 170 tons/hour. This furnace was fully screened. The study confirmed that contrary to assertions by other authors the proportion of direct heat transfer is quite low when burning natural gas. It is of interest to compare experimental data on heat transfer in the furnace in uestion with values calculated by the standard methods In Rg 7 the temperature at the outlet from the furnace iE plotted in dimensionless coordinates as a function of the ratio of Boltzmann's criterion to the blackness factor of the furnace. It will be seen that the experimental results lie close to the theoretical curves. The relatior ship between theoretical and calculated values of the gas Card temperature at the outlet from the furnace is plotted in 3/4 Fig 8 and shows that in general the calculated values are about 40 OC too high. It is concluded that the standard SOV/96-59-10-6/22 An Investigation of Radiant Heat Exchange in the Furnace of a Boiler when Burning Natural Gas method of making thermal calculations gives satisfactory results when applied to small furnaces burning gas. It appearsq however, that the emission properties of a natural gas flame have some special features that are not reflected in the standard formulae; thIs Is why measured values of outlet temperature are lower than the Card calculated ones. 4/4 There are 8 figuresq 1 table and 6 references, of which 5 are Soviet and 1 English.

No. .1, pp~ 56-58 TEXT; Heat exchange between-a body and a flow of air depends, amongst other things, on the roughness of the surface. In addition to studying this point it was desired.to obtain data with which to improve various design formulae. Tests were made on a 7-row square arrangement tube bundle made up with tubes ranging from 15.2 to 38.2 mn in diameter. Details are given about the tube arrangements and geometry. The tests were made in an open wind tunnel with a cross-section of 250 x 250 mm. with isothermal air flow, the Rovnolds number ranging from 7000 to 100 000~ Further informa-~-ion is given about the test conditions. Minimum roughness was obtained with the tube surfaces polished and chromium plated to prevent corrosion. 'Such surfaces were defined as having zero roughness. Maximum roughness was created by knurling and intermediate values were obtained by turning on a, lathe. The class of surface finish Card 1/3 E6.1471 S/096/61/000/001/008/011+ 3194/E18)+ The Influence of Roughness on the Aerodynamic Resistance of Tube Bundles in a Transverse Flow of Gas was determined with a.binocular microscope. From the test results plotted in Fig. 1 it will be seen that the data relating to polished tubes and to those with rough machined surface lie on practically a single straight line. Accordingly, there is no appreciable turbulence of the boundary layer with roughness up to 0.001 and there is no effect of critical resistance such as occurs when the point of break away of the flow from the tube surface alters. Accordingly, the subsequent tests were made'orily with tubes of minimum and maximum roughness. The influence of relative roughness is clearly seen in Fig. li beyond the critical point the greater the roughness the greater the increase in resistance as the Reynolds number rises. The critical point depends upon the height of the asperities on the rough surface. Data are tabulated which show that roughness has no Influence on the exponential to which the Reynolds number is raised when written as function of the Euler number. It is shown that existing design formulae may be ased in the range of Reynolds numbers from 6000 to 15 000 for tube Card 2-/ 3 864n S/O 66/61/000/001/008/014 919VE184 The Influence of Roughness on the Aerodynamic Resistance of Tube Bundles in a Transverse Flow of Gas roughnesses (ratio of asperity height to diameter) of 0.006. The mechanism of ?esistance is briefly considered and it is concluded that breakaway of the fluid flow from the surface governs the frontal resistance of a cylindrical tube, and previous work has shown that the frontal. resistance of a. tube bundle Is about 90% o." the total resistance. Curves of pressure distribution around tub; circumferences may be used to determine frontal resistance, and Fig.2 shows such curves for tubes of the 6th row of a bundle for three values of Reynolds number. When the surface is rough the flow breaks away from the tube area, creating a greater pressure depression behind the tube so that the frontal Tesistance inoroases. For low values of Reynolds number experimental points for difforent values of roughness lie on a single curve. There are 2 figures, 1 table and 7 Soviet references.
