摘　　要：依据大量生产资料,分析了锦界煤矿的充水因素、涌水规律及影响矿井涌水量的主要因素。研究得出锦界煤矿的主要充水通道为煤层开采所形成的导水裂隙带,矿井主要的直接充水水源来自中侏罗统直罗组风化基岩孔隙裂隙潜水-承压含水层,次为第四系上更新统萨拉乌苏组潜水含水层;回采工作面是矿井涌水的主要来源地,次为采空区;矿井经过5年的开采涌水量已达到顶峰,目前已呈现出缓慢平稳下降的态势;影响矿井涌水量的主要因素为煤炭产量、采空区面积及上覆风化基岩厚度。The water filling factors, gushing water law and main factors affecting mine water inflow for Jinjie Mine are analyzed based on a large number of production data. The research indicates that Jinjie Mine＇s main water filling channel is water flowing fractured zone formed by coal seam mining, main direct water filling source is from the weathering bedrock pore fissure water - confined aquifer of mid- dle jurassic Zhiluo group, secondly is from the phreatic aquifer of Quaternary upper Pleistocene Series Sarah WuSu group ;working face is the main source of mine water gushing, then is from goal. After five years of mining, water inflow has peaked, and currently shows a tendency of slow and steady decline. The main factors affecting mine water inflow are the coal production, mined - out area and thick- ness of overlying weathering bedrock.
