黄玉川煤矿三盘区奥灰水探查设计研究

Research on the exploration design of Ordovician limestone water in Huangyuchuan Coal Mine

黄玉川煤矿目前主采的煤层4#煤、6上煤属于石炭二叠系煤层,受奥灰水威胁严重。根据矿井5年采掘接续计划,在开拓三盘区前需查清三盘区奥灰水富水性、断层及陷落柱等隐伏导水构造发育情况,提前消除采掘过程中的奥灰水害威胁,为采掘布置提供可靠依据。结合矿井的水文地质条件,提出了奥灰水探查主要采取地面勘探与物探相结合、井下超前物探和钻探相结合的方法,以达到探查奥灰水的目的,也可以为类似水文地质条件矿井的奥灰水探查设计提供借鉴。

The main mineable coal seams in Huangyuchuan coal mine are threatened by Ordovician limestone water seriously. Before the mining of the third mining area,for identifying the water yield property of Ordovician limestone water and the hidden structures of faults and collapse columns,combined with the mine hydrogeological conditions,the comprehensive method of the ground geophysical prospecting and exploration,underground advanced geophysical prospecting and drilling exploration was proposed. The research can provide reference for the exploration design of Ordovician limestone water in other coal mines with similar hydrogeological conditions.
