中文摘要：

针对恒源煤矿为解决太灰含水层高压水害,需要对其进行疏干降压从而导致陷落柱有活化导水可能性的问题,运用数值模拟软件Comsol Multiphysics模拟渗流作用下特征离子Ca2＋、HCO3-在距离陷落柱中心一定范围内浓度的变化趋势,根据太灰水长期抽水试验和观测孔水位变化数据确定水位异常值为-5-＋1 m/月。结合电阻率变化趋势,建立完整的监测预警系统,以保证矿井安全生产。

英文摘要：

For the problem of the possibility of collapse column water activated by mine dewatering in Hengyuan coal mine, then use the numerical simulation software Comsol Multiphysics to simulate the characteristic chemical ions Ca^2＋, HCO3^- concentration distribution with the change of distances from the center of the collapsing column. According to Hengyuan coal mine Taiyuan formation limestone aquifer long-term pumping test and observation wells established the abnormal water level of -5-1 m/month. Combining resistivity trends, establish a complete monitoring system to ensure mine safety production.
