【摘要】 123下02工作面位于济宁三号矿十二采区东部，受孙氏店支断层与多煤层开采重复扰动的影响，工作面充水条件变得更为复杂。为了制定有效的防治水措施，保障工作面安全回采，需要对工作面涌水量进行预计。在对工作面充水水源，工作面导水通道特别是导水裂隙带发育情况进行分析后，为提高计算结果的准确性，根据矿井水文地质资料选取合适的水文地质参数后，针对含水层性质及充水水源不同，对工作面范围内的含水层采用不同的方法进行分层分部计算，采用解析法计算工作面上部含水层的涌水量，采用比拟法计算奥灰水对工作面侧向补给量，最终计算得到工作面正常涌水量158.6 m3/h，最大涌水量237.9 m3/h。更多还原

【Abstract】 123down02 working face is located in the east of No. 12 mining area of Jining No. 3 coal mine. Affected by the repeated disturbance of sunshidian branch fault and multi coal seam mining, the water filling conditions of the working face become more complex. In order to formulate effective water prevention and control measures and ensure safe mining of working face, it is necessary to predict the water inflow of working face. On working face water filling water, working face water channel, especially water diversion fracture zone development situation analysis, in order to improve the accuracy of the calculation results, according to the mine hydrogeological information select proper hydrogeological parameters, in view of the different aquifer properties and water filling water, on the face within the scope of the aquifer using different calculation method of hierarchical division. The analytical method was used to calculate the water inflow of the upper aquifer of the working face, and the analogy method was used to calculate the amount of Ordovician limestone water to the side of the working face. The normal water inflow of the working face was 158.6 m3/h, and the maximum water inflow was 237.9 m3/h.更多还原
