成庄矿1307工作面老空水治理技术

Goaf Water Treatment Technology in Chengzhuang Coal Mine 1307 Working Face

成庄矿1307工作面上方为3304工作面采空区,采用理论分析、数值模拟与现场实测相结合的方法,分析顶板导水裂缝带发育高度,确定1307工作面导水裂缝带发育高度为34.3~36.6 m,裂采比为31.18~33.27,存在涌水风险,通过在1307工作面回风巷实施探放水措施,保证了1307工作面稳定回采。

Above 3304 working face of Chengzhuang Coal Mine 1307 working face is mined-out area,adopt the measurement theoretical analysis and numerical simulation field measurement,It is determined that the development height of the water-conducting fracture zone on the 1307 working face is 34.3~36.6 m,split ratio is 31.18~33.27,the risk of water burst in 1307 face return air lane drain measures,to ensure the stability of 1307 face stoping.
