【摘要】 雅店煤矿位于彬长矿区北部,地质构造简单,主要可采煤层为延安组的4#煤层。通过对矿井水文地质条件的分析研究,认为对矿井安全生产有影响的含水层主要为富水性中等且水头压力较高的洛河组含水层,导水通道主要为煤层开采形成的导水裂隙带。提出了矿井井筒施工和煤层开采过程中,在防治水工作中应借鉴临近矿井的经验,加强首采工作面煤层采动前、后含水层变化规律及导水裂隙带发育规律的研究,采用超前探水、疏水降压、合理留设防水煤岩柱等防治水建议。更多还原

【Abstract】 The Yadian coalmine is located in north part of the Binchang mining area.Geological structure in the area is simple;No.4 coal in the Yanan Formation is the main mineable coal seam.Through coalmine hydrogeological condition analysis,considered that safety mining impacting aquifers have medium water yield and rather high head pressure Luohe Formation aquifers,water conducted channels are mainly water flowing fractured zones formed during coal mining.Advised that during the shaft construction and coal wining courses should use neighboring coalmine experiences on water control for reference,strengthen studies on first mining area working face aquifer variation patterns before and after coal mining and water conducted zone development pattern,adopt advance water detecting,water drainage pressure lowering,rational water barrier setting measures.更多还原
