The 6th 15-31010 face of the twelfth coal mine of Pingdingshan Coal Mining Co.,Ltd.is buried underground more than 1000m, which belong to high-gas working face.In order to solve the damage of ground stress to protective seam exploitation at inside final 200m,using technology of long hole loose blasting to relieve pressure.By analyzing and application of the depth and distance between of blast hole and sealing technology,we find out the method of by using deep-hole loose blasting technology to govern ground stress,and find out a new way of safe stopping of high-gas working face 1000m underground.
