深部煤巷条带区域双重卸压防突方法研究
Research on Double Pressure Relief and Outburst Prevention Method in Strip Zone of Deep Coal Roadway
摘要
Abstract
Aiming at the anti-burst in the deep high-stress coal roadway strip zone, we analyzed the influence of gas drainage on deep coal and gas dynamic disaster and revealed the new characteristics of disasters with increased ground stress-dominated outburst danger after deep gas drainage. We proposed the double pressure relief and anti-burst method of the coal lane strip area. It is that the pressure relief floor rock tunnel is pre-arranged at a certain distance directly below the coal road to be excavated to relieve the ground stress of the overlying rock mass on the roadway, at the same time, the dual pressure relief and outburst prevention method of strip area of coal roadway for pressure relief extraction by through-beds boreholes is used in combination, and applied to engineering practice. The practice shows that the pressure relief effect of the overburden coal and rock mass on the floor roadway is remarkable, and the pressure relief and extraction of the through-beds hole is significantly improved, which realizes the dual role of eliminating the stress hazard and gas hazard at the same time.关键词
