摘要
为消除15105工作面回采期间受上覆13101工作面采空区积水威胁,保证工作面安全回采,采取理论计算、数值模拟分析试验等方法,同时在15105工作面运输顺槽打孔进行现场实测验证,确定该工作面导水裂缝带发育高度为53.8~55.7 m,裂采比为31.9,有空区涌水威胁。在15105工作面运输顺槽进行探放水,对上覆13101工作面老空积水进行充分释放,共排水36 300 m^(3)。
In order to eliminate the threat of stagnant water in the goaf area of the overlying 13101 working face during the mining period of the 15105 working face and ensure the safe mining of the working face,the methods of theoretical calculation and numerical simulation analysis experiment are adopted,at the same time,the transportation channel of the 15105 working face is punched for field measurement verification.It is determined that the development height of the water conducting fracture zone of the working face is 53.8-55.7 m,the split-mining ratio is 31.9,and the threat of water gushing in the empty area is determined.The exploration and discharge of water is carried out in the transportation channel of the 15105 working face,and the old empty stagnant water in the overlying 13101 working face is fully released,with a total drainage of 36 300 m^(3).
