Chief Engineer Gerhard Thuerling of Alt-Frie dr~chsfelde 126 in Berlin-
Friedrichsfelde and by Engineer Stimper (fnu). The equipment applies to both
open-pit and underground mining. In the introduction reference is made to
the fact that VEB Funkwerk Koepenick in East Germany is producing such equipment.

For thermal reasons higher loads are not admissible. 'When

between the rotary sigMll ng and recnivinj sets is not longer

Prior to eifting the devices grid transmitting, instaflattone
in question, I bed to make some general remarks upon the haul-
age t echnio s.

la to the heulin41 w ork there woo' the problem to replace the
heavy physical. work by meehentcrt devieec, .i.e. by raaachines
doing, it. The quick promtilg tjon nn d, inpcnious utilization of
electric ongineeringhgsa permitted a broad ntachtn.izrtion.
Lapeeielly the electric machine,iq capeble of concentra tiny;
large quantities of enerp,-y tit spatially limited places, reap.
of repeating the same .operation for moving heavy messes and
loads nearly ,infinitively often without any fatigue. such work
nowvadp,ye ie not- longer expected to be done by men.
In thee line of winning engine crint such an example is
given by the service of lore winning devices - the rubbish

wtchani:ring the. work to such an extent that, on the eontrcry
to former working methods, only e fraction and insl.gnificent
percentage of labours rre required who have been act free for
new teeka and work.
From the 114etorical point of view the use of the rubbish
?onveyizi bridges is still rather new. The first equipment
of this kind rua4ng on mils hen been put to service in
Germany in 1 24 for winawnin.g of lig.aite n'bove ground, i.e. for
reraovi the facing lnyerc cons i n tin of send, clay, and other
matters. The initially met problems end difficulties have ',een
surmounted already after a short time, and that in a quite

are connected with t is mss bridge. According to the ivor]"'ing
conditions the oon.otructiontnl deem may be different. On the
left side of the picture one scraper and 2 d i to?iers removing
the rubbish are showtn. The rubbish is trnnsported, by means
of belt conveyors, over the main bridge, and put down on the
dump aitun}ted on the right side. In the middle we soe the
bare lignite with the travollinC, treo3 laid upon it. The span
of the " aveTling gears of a rubbish conveying bridge. differs
ncdorcding to the geological conditions in c nestion, --nd ranged
between 80 and 200 ma. The travelling speed of P. rubbish con-
veying bridge amounts to about 6 me/p.m. In dependence on the
.vorkin ; requirements several scrapers axed ditchers may be
adjoined to one rubbish conveying bridge.
Figure :rno.2 shows a compound
dredltng machine. On one side, in
front to the left, a ditcher, and
in front to the right r, alew-ing
sarapernre arranged. The dredger
runs on rails. In connection with
rth.: rubbish convening bridge pre-
ferably slowing dredgers are used.
These machines, rurn:iing partially
on onterpi:llars or also on rails,
lead the dredged material through
U Z-2 i)red -i ~faehine a fee ling belt to the rubbish-con-
veying bridge. Up to now there are
different designs and eonstruotiofas of dredging rmchtnes in
accordance to the working trequirernenta. Efforts are made,
however, *to develop a so-called standard design meeting poo-
sibly all rdox -ins, requirem nts in connection with the rubbish
