Description
ведут опускными блоками, которые в первую очередь отсекают прорезными восстающими щел ми от боковых пород и массива угл с оставлением целиков, затем осуществл ют подсечку блоков у их почвы и в дальнейшем после опускани блоков под действием обрушенных пород производ т гидроотбойку блоков горизонтальными сло ми.They are driven by lowering blocks, which are first of all cut off by slit reaming slots from the side rocks and coal mass, leaving the pillars left, then they are hooked down to the soil and then, after the blocks are lowered, the layers are hydroformed by horizontal layers.
