摘要

针对蒙陕接壤区深埋煤层顶板水文地质条件复杂、矿井涌水量不清等问题,分析了巴彦高勒煤矿首采面顶板含隔水层结构特征,确定3-1#煤层顶板导水裂缝带范围内的含水层,采用动静储量法计算得到首采工作面不同回采阶段涌水量,涌水量计算值与实际值较吻合,为工作面排水系统建设和矿井水防治提供了科学依据。
        Aiming at the complex hydrology condition and uncertain mine water inflow of deep buried coal seam roof of contiguous area,this paper analyzed the structural characteristics of aquifer and aquifuge of first mining face roof at Bayangaole Coal Mine and determined aquifer in scope of water-conducted fractured zone of 3-1~# coal seam roof.Static and dynamic reserve method was used to calculate the amount of water inflow during each back-mining period at first mining face.The calculated water inflow magnitude was fabricated with the actual value and provided drainage system establishment of mining face and mine water safety with scientific evidence.
