摘　　要：根据采矿地质条件背景以及最新地质资料的分析,论述了该矿区水文地质特征、充水因素,并在此基础上采用比拟法对研究区矿井涌水量进行了预算。结果显示:区内充水水源以地表水及含水层中地下水为主,断层带、岩石天然节理裂隙及人为采矿冒落裂隙提供了主要充水途径;比拟法预算最大涌水量为2.71×10^3m^3/d,三岔河凹河段补给量为3.59×10^2m^3/d,正常涌水量为两者之和3.07×10^3m^3/d,最大涌水量为正常涌水量的2.4倍,即最大涌水量为7.37×10^3m^3/d。比拟法采用实测的涌水量资料计算,结果可靠,可采用7.37×10^3m^3/d作为今后井田选择排水设备的依据,研究思路可为类似矿井的水文地质分析提供参考。According to the background of mining geological conditions and the analysis of the latest geological data,the hydrogeological characteristics and water-filling factors of the mining area are discussed,and on the basis of this,an analogy method is used to estimate the mine water inflow in the study area.The results show that the water source in the area is mainly surface water and groundwater in the aquifer,and the fault zone,rock natural joint fissures and artificial mining caving fissures provide the main water filling pathways;the maximum water inflow estimated by the analog method is 2.71×10^3 m^3/d,the recharge amount of Sanchahe Ao reach is 3.59×10^2 m^3/d,the normal influx is 3.07×10^3 m^3/d,the maximum influx is 2.4 times the normal influx,that is,the maximum influx is 7.37×10^3 m^3/d.The comparison method uses the measured water inflow data to calculate,the results are reliable,and 7.37×10^3m^3/d can be used as the basis for selecting drainage equipment in the future.The research ideas can provide a reference for hydrogeological analysis of similar mines.
