摘要
矿井涌水会恶化采掘工作面的工作环境,引发灾害,严重影响矿井的安全生产和职工的生命安全。为了保证三元煤业的安全生产,对该矿3号煤层开采过程中涌水量与各个充水因素进行综合分析,认为大气降水对矿井涌水量的影响较小,可以忽略不计;产量和回采面积对矿井涌水量具有一定的影响,但总体上影响不大;矿井涌水量主要受采空区积水影响。在此基础上提出了加强基础地质资料收集、采用物探和钻探技术手段加强对采空区积水探测等防治水对策,为矿井的安全生产奠定了基础。
Mine water inflow would deteriorate the working environment of mining face,cause disasters,and seriously affect the mine production safety and the life safety of workers.In order to ensure the safe production of Sanyuan Coal Industry,the water inflow and each water filling factors in the mining process of No.3 coal seam were comprehensively analyzed.It was considered that the influence of atmospheric precipitation on mine water inflow was small and could be ignored.The yield and mining area had a certain impact on the mine water inflow,but the overall impact was not significant;the mine water inflow was mainly affected by the water accumulation in the goaf.On this basis,it was proposed to strengthen the collection of basic geological data,use geophysical detection and drilling detection techniques to strengthen the detection of goaf water and other water prevention and control countermeasures,which laid a foundation for the safe production of the mine.
