Abstract

Due to the complex geological conditions of Nanshan mine east region, the outburst predict index overrun frequently in the process of high-dipping extremely thick coal seam rock cross-cut coal uncovering, this text designed and optimized the front explore borehole parameter to ascertain conditions of coal seam; Optimized gas drainage drilling parameters to improve the rate of extraction, reduced the blank tape; On the basis of the theory of mechanics, derivate the computational formula of minimum safety rock pillars, identified with the minimum thickness safety of rock pillars. Through the above measures, guaranteed debunking coal seams quickly and safely.
