| description | The invention belongs to the field of coal mine earthquake prevention and control, and particularly relates to a coal mine earthquake prevention and control method for a deep stress concentration area. According to the method, firstly, the coal pillar between the two main roadways in the main roadway coal pillars is stoped in a filling mode, under protection of the coal pillars on the two sides of the two main roadways, safety can be guaranteed, mine earthquakes can be prevented, and meanwhile, the filling bodies after filling can prevent the coal pillars on the two sides of the two main roadways from forming island coal pillars during stoping; therefore, mine earthquakes can be avoided when coal pillars on the two sides of the two main roadways are stoped. Only the coal pillar between the two main roadways is filled in the whole main roadway coal pillar, the filling workload is small, the filling proportion is small, and the mining efficiency of the whole main roadway coal pillar is high.
