Abstract

In order to improve the concentration and pumping volume of gas control drilling hole in the cross-cut uncovering area, reduce the pre-pumping time of outburst coal seam, principle of broken coal based on high pressure water jet, the mechanism of high pressure water jet punching to relieve pressure and increase permeability is studied, through theoretical analysis and practical application, the effect of high pressure water jet punching on gas control is expounde, the results show, Coal seam after the implementation of hydraulic punching measures, the elastic potential of the coal has been released, effectively eliminate the stress to stimulate the protruding, with better relief effect of pressure relief, effectively improve the extraction of gas concentration and pumping volume, to achieve a safe and rapid regional out of conflict. In this paper, the research and application of high pressure water jet pressure relief and gas permeable control technology in 700m central pedestrian oblique well in Xinji No.1 Mine are introduced.
