The stability of goaf surface is a key problem hindering the exploitation and utilization of goaf surface. By reproducing the process of goaf formation, the stability law of goaf is explored, and then the concept of load transfer depth is proposed [1], so as to obtain the method of calculating the surface carrying capacity of goaf, providing certain reference for the development and utilization of surface land resources in goaf in China.
