STUDY ON BEHAVIORAL LAWS OF STRATA PRESSURE OF COAL FACE AND ITS CONTROL IN THIN SEAM
Based on the geological conditions of thin seam with hard roof and soft coal at Caoyao Coal Mine, Yima Coal Group, China, the behavior of strata pressure in coal face was studied with numerical calculation, overall process of first weighting and periodic weighting was reappeared and the related parameters of abutment pressure in front of coal face were obtained. According to the classification of stability and controllability of roof strata, support pattern of coal face in thin seam at Caoyao Mine were proposed. In view of the calculation results, the scheme of feasible matched equipments of coal face in thin seam was accordingly put forward. The conclusions have provided fundamental basis for mechanization mining thin-seam, and have advanced the theory for technology on mining thin seam.
