Abstract

According to the energy development policy and energy structure adjustment in China, this paper puts forward the utilization strategy of goafs based on correspondence analysis. Firstly, the correspondence analysis was used to discriminate the goafs with hidden collapse risk and research the collapse rules in coal mine. Using this method, 7 variables which affected the collapse of coal mine goaf and 24 samples were analyzed by R factor analysis and Q factor analysis to complete the distribution picture of variables and samples. The variables included degree of complex geological structure, goaf volume rate, vertical depth away from the surface, dip angle of coal seam, number of spatial superimposed layers, overburden thickness and overburden type. The analyses were conducted by the distribution picture to research the collapse rule of goafs. The corresponding measures could be taken to treat the goafs according to collapse rule. Secondly, the projects of establishing underground water storage system, underground oil and gas storage system and underground waste disposal system were proposed to realize the goafs utilization.
