| 摘 要： | 以余吾煤矿为研究对象,介绍了矿井的水文地质特征,提出了3号煤的直接充水含水层为3砂、三灰。采用无限边界的承压一无压公式计算余吾矿正常涌水量为316.61 mVh,最大涌水量为398.4 mTh,并分析了相邻煤矿采空区积水目前对矿井生产影响不大,本井田3号煤采空区积水对生产影响较大,并通过公式计算得到3号煤层采空区积水量为381.7km3.

| Abstract: | Taking Yuwu Colliery as the research object,the hydrogeological characteristics of the mine are introduced in the paper,and the direct water-filled aquifer of No.3 coal mine is also proposed as 3 sand and 3 ash.The pressure-without pressure formula of infinite boundary is used to calculate the normal water inflow of Yuwu Colliery is 316.61 m3/h and the maximum water inflow is 398.4 m3/h.The water accumulation in the mined-out area of the adjacent coal mine has little effect on the mine production,while the water accumulation in the mined-out area of No.3 coal in this mine field has a greater impact on the production.According to the formula,the water accumulation in the goaf of No.3 coal seam is 381.7 km3. |
