Abstract：Studying the distribution state of cracks and bed separations of the overburden strata is a pr-requisite to master the gas flow rule in the gob and finally carry out gas drainage from the gob. In this paper, based on the test results of rock mechanics in the laboratory, combining with the geologic and mining conditions in No. 1201 fully mechanized working face in Fusheng Mine and using ANSYS software, an elastic-plastic stope model was established, research was made on the distribution regularity of the stope surrounding rock stress and the mining crack field as well as the distribution characteristics of the surrounding rock's fracturing space, the distribution of the“three-area” and“three-zone” in No. 1201 working face was simulated, the arrangement and parameters of high-level boreholes in the roof of this face were optimized, so better gas drainage effect can thus be obtained.
