Abstract
By comprehensive analysis of time and space factors which affect the ground stability of coal mining subsidence area,the method of evaluation and regionalization of ground stability of coal mining subsidence area is proposed.The mining subsidence area can be divided into stable area,temporary stable area and instable area.Ground stability of coal mining subsidence area must be evaluated before the treatment project.The treatment projects of different ground stabllity area must be different.
