Abstract
СПОСОБ У/ ЛЕНЬШЕНИЯ ПРИТОКА ВОДЫ В ГОРНЫЕ ВЫРАБОТКИ . ---../ ПРИ РАЗРАБОТКЕ УГОЛЬНЫХ ПЛАСТОВ , включающий осушение обводненных пород путем предварительной отработки одного из пластов на рассто нии L от обводненных пород, определ емом из соотношени 0,5 L HT-, где Н- - высота зоны водопровод щих трещин, образующихс над выработанным пространством разрабатываемого пласта, отличающийс тем, что, с целью повышени эффективности осушени обводненных пород за счет рациональной последовательности разработки пласта, предварительно осуществл ют разработку на участке пласта, глубина залегани которого под обводненными породами не превышает 0,8 Н , а затем в восход щем пор дке осуществл ют разработку части пласта, § расположенной со стороны восстани от (О ранее отработанного участка. 4METHOD OF WRINKING / WRINKING THE MOUNTING IN THE MOUNTAIN PROCESSES. --- .. / WHEN DEVELOPING COAL STRAYS, including draining watered rocks by pre-mining one of the layers at a distance L from watered rocks, determined from a ratio of 0.5 L HT-, where H- is the height of the zone of water conducting cracks, formed over the developed space of the developed reservoir, characterized in that, in order to increase the efficiency of drainage of watered rocks due to a rational sequence of reservoir development, preliminary development is carried out on the section of the reservoir orogo under watered species does not exceed 0.8 N and then into ascending order is performed to develop part of the formation, § situated side by uprising (O previously exhaust section. 4
