Изобретение относитс к горной промышленности и может быть использовано при разработке свит угольных пластов дл уменьшени притока воды в горные выработки .The invention relates to the mining industry and can be used in the development of coal seam formations to reduce the flow of water into the mine workings.
Известен способ уменьшени притока воды в горные выработки при разработке угольных пластов, включаюший предварительное осушгние обводненных пород посредством проведени комплекса дренажных выработок 1.There is a method of reducing the inflow of water to the mine workings during the development of coal seams, including the preliminary drying of water-cut rocks by conducting a complex of drainage workings 1.
Известен также способ уменьшени притока воды в горные выработки при разработке свит угольных пластов, включаюший предварительное осушение обводненных пород , залегаюших в кровле подлежашего. отработке пласта 2.There is also known a method of reducing the inflow of water to the mine workings during the development of coal seam formations, including the preliminary drainage of watered rocks that lie in the roof of the subsoil. reservoir mining 2.
Однако известные способы характеризуютс значительными затратами на дренажные работы и недостаточной эффективностью .However, the known methods are characterized by significant drainage costs and lack of efficiency.
Цель изобретени - сокращение затрат на дренажные работы при эффективном осушении горных пород.The purpose of the invention is to reduce the cost of drainage work with effective drainage of rocks.
Поставленна цель достигаетс тем, что предварительно отрабатывают один из нижележаших пластов свиты, удаленный от обводненных пород на рассто ние L, удовлетвор ющее условию 0,, гдеThe goal is achieved by preliminarily working one of the lower strata of the suite, which is removed from the watered rocks by a distance L, satisfying condition 0, where
Ят - высота зоны водопровод ших трещин, образующейс над выработанным пространством нижележашего пласта.Yat is the height of the zone of water-borne cracks, which is formed above the developed space of the lower formation.
Способ заключаетс в следующем. При отработке свиты угольных пластов при наличии обводненных пород, залегаюших в кровле подлежащего отработке пласта, в первую очередь отрабатывают один из нижележащих пластов, удаленный от обводненпых пород на рассто ние L, удовлетвор ющее условию 0,, где Ят - высота зоны водопровод щих трещин, образующейс над . выработанным пространством нижележащего пласта. Такое удаление обеспечивает поступление воды в выработанное пространство нижележащего пласта при его отработке без опасности дл очистного забо , при этом происходит одновременное осушение обводненных пород.The method is as follows. When mining coal formations in the presence of watered rocks that lie in the roof of the formation to be tested, first of all work out one of the underlying layers that is removed from the watering rocks by the distance L, satisfying condition 0, where Yat is the height of the water conducting cracks zone, forming over. developed by the space of the underlying reservoir. Such removal ensures the entry of water into the developed space of the underlying reservoir during its development without danger to the clearing site, and simultaneous drainage of the watering rocks occurs.
Предлагаемый способ позволит сократить затраты на дренажные работы при эффективном осушении горных пород.The proposed method will reduce the cost of drainage work with effective drainage of rocks.
