Prediction of coal mine water inflow by different mining methods and environment impact analyses

  • 摘要: 煤矿开采不当会对水资源与水环境造成破坏,尤其在生态环境相对脆弱地区更是如此。针对目前矿井涌水量预测大多以单一工作面或煤矿为评价单元,对沟域内煤矿群同时长期开采的地下水环境影响重视不够。选择头道河则沟域为研究区,以地下水勘查、井田勘探资料为依据,构建了头道河则完整沟域的地下水三维非稳定流数值模型,根据地下水、地表水监测数据和煤矿群开采涌水量的长观资料进行模型的识别与验证,以9#煤矿为典型矿区,分析综采和条带充填2种不同开采方式下矿井涌水量及其对水环境的影响。研究结果表明:(1)综采状态下,矿井涌水量增加0.70×104 m3/d,导致地下水溢出量减少0.20×104 m3/d,引发矿区及区域地下水水位下降0.21~17.92 m;条带充填开采状态下,矿井涌水量增加0.11×104 m3/d,导致地下水溢出量减少0.04×104 m3/d,引发矿区及区域地下水水位下降0.01~0.44 m。(2)煤矿按综采方式开采,导水裂隙带高度大,将大面积导通第四系潜水含水层,矿井涌水对水环境影响较大;若按条带充填方式开采,导水裂隙带高度大幅变小,不会导通第四系潜水含水层,矿井涌水对水环境影响较小。煤矿企业在煤层上覆岩层厚度较薄的地段采煤时,宜采取条带充填开采的方式。研究结果可为研究区或类似煤田开采方案制定、科学处理好煤炭资源开采与生态环境保护关系等提供依据或参考。
