Abstract

Based on the mechanism of composite energy and its energy scale, evolution and distribution law of stress and fracture field in surrounding rock of roadway in deep mining, the article puts forward regional outburst prevention measures of unloading pressure by pre excavation rock roadway and constructing wear layer drilling to pump coal roadway strip gas, a complete set of technical system of regional outburst prevention in coal roadway strip by pre excavation and unloading floor roadway in the Fengcheng mining area is obtained. The field practice shows that regional outburst prevention in coal roadway strip is carried through pre excavation of floor roadway which layout in the bottom of the bottom of the coal roadway 8~12m to carry on the pressure relief combined with wear layer drilling drainage gas, it can greatly improve the permeability of coal seam and the effect of pressure relief, and ensure the safe and fast roadway excavation.
