    • Abstract
  • On the basis of summarizing strata behaviors of 42106 fully mechanized coal caving face, according to the comprehensive analysis of field survey and measured results, it is found that there is a certain degree of impact in 42106 fully mechanized caving face in the recovery process and its production process. According to the actual situation in mine and the theory of rock stratum control in the mining area, the laws and the influencing factors of strata behaviors in 42106 fully mechanized face are discussed, and the hydraulic fracturing and pressure relief on the roof of the working face is further proposed. The results of field construction show that the pressure relief and unloading of the roof can reduce the degree of pressure appearance and stress concentration of stope.
