红石岩煤矿水文地质特征及矿井充水因素分析

Analysis on mine hydrogeology characteristics and water filling factors in Hongshiyan coal mine

红石岩煤矿随着开采面不断扩大和开采程度不断加深,矿井水文条件对煤矿正常生产影响越来越大。结合矿井含水层和隔水层分布规律,分析了大气降水、井田水、地表水对矿井充水的影响,通过对导水裂隙带发育高度计算,对矿井充水通道进行分析,结果表明矿井在未来开采过程当中,随着煤炭产量的加大,采空区面积和导水裂隙带高度的增大,矿井涌水量会进一步增加,矿井充水强度也必然会增大。

With the expansion of mining area in Hongshiyan coal mine, the mine hydrogeologieal conditions have more and more influence on the normal production of coal mine. Combined with the distribution law of mine aquifer and aquiclude, the influence of atmospheric precipitation, formation water and surface water on mine water filling was analyzed. By calculating the height of the water flowing fractured zone, the water filling channel of the mine was analyzed. The results show that with the increase of goaf area in the future, mine inflow will increase further and the water filling intensity will also increase.
