Abstract

Taking the return air lane of 8201 working face of a mine as the research object, statistically analyze the microseismic monitoring and the change of mine pressure data before the occurrence of the impact mine pressure accident in the process of mining back. Summarize the cut top pressure along the empty stay in the case, microseismic monitoring impact pressure early warning information law, as a similar condition of the mine under the impact pressure prevention and control basis. The corresponding prevention and control measures have been proposed and implemented, and good control effects have been achieved. These measures effectively guarantee the safe production of coal seam mining.
