Beschreibung
Zusammenfassung:	The invention provides a mining subsidence area division method. The mining subsidence area division method comprises the steps that three-dimensional geologic feature data of a subsidence area in the current state is acquired, and the subsidence area is preliminarily divided into a complete occurrence area and a goaf occurrence area at least according to the three-dimensional geologic feature data; confirming an activation risk area in the mined area occurrence area; establishing a three-dimensional geologic model of the goaf in the subsidence area, wherein the three-dimensional geologic model is used for carrying out a numerical test and a three-dimensional model test on the goaf in the goaf occurrence area; performing a numerical test according to the three-dimensional geological feature data to determine the type and the influence range of the activation risk area under the non-treatment condition; performing a three-dimensional model test on the goaf in the influence range of the activation risk area to
