Abstract: In order to eliminate the danger of coal outburst of low permeability and high gas coal seam in Guizhou Mine, we take Xintian Coal Mine 1401 working face as the research background, according to the underground pressure distribution law and the separation control function of drainage borehole, we make study and test three-opening layout by two day cycle, coordinated with long and short drillings, to achieve a long borehole to release pressure, short hole to drainage cross step type shallow hole drainage technology. The industrial experiment shows that the long and short drillings coordinate with shallow hole drainage technology can effectively improve the effect of drilling gas emission, significantly reduce the danger of coal and gas outburst in coal mining ground.
