集贤-东荣矿区水文地质条件及矿井充水条件分析

Hydrogeological Condition and Mine Water Filling Condition Analyses in Jixian-Dongrong Mining Area

集贤-东荣矿区是黑龙江省重要的大型煤产地,由于过去几十年的强力开采,致使其资源储量及水文条件发生较大变化,给矿区安全生产带来风险。通过对矿区水文地质条件及矿井充水条件的分析,认为矿井的直接充水来源为地下水含水层和老空积水;矿井的主要的充水通道为断裂构造,其次为采动裂隙、封闭不良钻孔。

The Jixian-Dongrong mining area is an important large coal production base in Heilongjiang Province. Since high strength exploitation during past decades, made its resources and reserves and hydrogeological condition changed a lot, and brought risks in mining area production safety. Through mining area hydrogeological condition and mine water filling condition analyses, have considered that the mine direct water filling sources have groundwater aquifer and gob area ponding. Faulted structures are the main mine water filling channels, secondary mining fractures and poorly sealed boreholes.
