摘要
兴隆庄煤矿十采区的主采煤层是3煤层,其直接充水含水层是煤层顶板砂岩水。在分析采区3煤顶板砂岩水充水特征的基础上,采用解析法,预测其静储量总体约为34万m3;根据不同参数值进行分区计算,得到了十采区工作面在不同推进速度下的涌水量。研究结论可为兴隆庄矿十采区下一步的安全开采提供设计和决策基础地质条件保障,同时也可以为其他类似水文地质条件的采区工作面的涌水量预测提供理论依据。
The No.3 coal seam is the main mineable coal seam in No.10 winning district in the Xinglongzhuang coalmine,its direct water filling is from coal roof sandstone aquifer.Based on the analysis of water filling characteristics,using analytic method predicted its total static water reserve is about 0.34 million m3.According to different parameter values to carry out partitioning computation,has acquired water inflow under different advancing speed in No.10 winning district working faces.The result can provide design and decision basic geological condition guarantee in next safe production,meanwhile can provide theoretical basis for water inflow prediction in other winning district working faces with similar hydrogeological condition.
