桑树坪二号井顶底板水害超前探查与治理技术研究

Study on Sangshuping No.2 Mine floor water damage advanced detection and control technology

水害是影响煤矿安全生产的五大自然灾害之一,煤系地层顶底板砂岩裂隙水是主要充水水源。为将顶底板水害超前查明、超前治理,减小煤炭开采成本、确保矿井安全生产,针对桑树坪二号井3307工作面,在巷道掘进期间采用物探、化探、钻探探查超前对回采工作面水害进行治理。利用高程自流导排水,对污水源头进行治理,做到绿色环保高效开采,并为相似矿井顶底板水害超前探查与治理提供参考。

Water damage is one of the five major natural disasters affecting coal mine safety,and water from the sandstone fissures at the top and bottom of the coal system is the main water source.In order to identify and manage the water damage at the top and bottom of the roof and floor in advance,reduce the cost of coal mining and ensure the safety of mine production,based on the 3307 working face of the No.2 mine of Sangshuping,during the roadway mining,the physical and chemical detection advanced technology was adopted.The high elevation self-flow diversion drainage was used to control the source of sewage,so as to achieve green environmental protection and efficient mining.The technology provided reference for the advanced exploration and treatment of water damage in the top and bottom of similar mines.
