Paper Title:
Study on Prevention and Control Technique of Ground Pressure in Fully Mechanized Mining Remained Coal Pillars
  Abstract

Based on the strong danger and great difficulty characteristics of coal pillars mining under strong ground pressure in Datong coal district, the observations on the No.311 coal face in Tongjialiang coal mine were carried out by the method of drilling bits. The key zone of ground pressure prone was determined and the effective unloading measures by blasting were also taken to mining coal pillars by fully mechanized mining technique.
