Abstract：The failure process of overburden in filling mining is different from that in caving mining. In order to study the development process of “two belts” of overburden in filling mining， the mechanical model and the calculation method of “two-belt” height is constructed by applying the shell theory. It is concluded that when the change of equivalent mining height broken a certain critical value， the height of the two belts will jump. Taking the working face of Xima coal mine 1327 as the research example， the mechanical model and calculation method are adopted to analyze the fault zone height of 1327 working face after filling mining， and the height of the collapse zone is 0m. The fault zone height of 1327 working face was 10.7 m in the field， and no collapse zone was found. The theoretical analysis is consistent with the results obtained in the field， and the mechanical model and calculation method is more accurate.
