通过对矿区含、隔水层及断层带水文地质特征的分析和井下水文地质现象的观测,认为目前矿井开采煤层较浅,以二1煤顶板直接含水层充水为主,水量不大;但随采掘的延深,煤层下伏的太原组灰岩和奥灰含水层,会在断层的影响下,与其它含水层发生水力联系,对矿井开采形成威胁。根据对矿井充水因素的分析结果,指出目前矿井的充水强度不大,充水通道主要为断层带,在开拓-800m水平时,应注意构造破坏或隔水层薄弱地段,此地段有可能出现奥灰水突入矿井的危险。为防止矿井突水,提出了建立健全地下水观测系统,加强井下钻探和物探工作,重视邻近矿井老窿水监测等矿井水害防治工作建议。
Based on the analysis of the hydrogeological features of the aquifer, aquifuge and fault zones and the observation of downhole hydrogeological phenomena, it is considered that the coal seams in the mines are relatively shallow at present. With the deepening of the digging, the Taiyuan Formation limestone and the Ordovician limestone aquifers underlying the coal seam, under the influence of the fault, will have hydraulic connection with other aquifers and pose a threat to mine exploitation. Based on the analysis of the water filling factor of the mine, it is pointed out that the current water filling intensity of the mine is not large and the water filling channel is mainly a fault zone. At the level of -800m, attention should be paid to structurally damaged or impervious sections. Occurrence of gray water into the mine danger. In order to prevent the water inrush from the mine, the paper put forward some proposals of establishing and perfecting the groundwater observation system, strengthening the underground drilling and geophysical exploration work, attaching importance to the monitoring and control of the mine water damage in the adjacent mine.
