Abstract: In order to improve the efficiency of gold mining, reduce the mining cost and dilution rate, and strive for the safe and sustainable exploitation of the metal resources in the enrichment area in the shortest time, In this paper, firstly, aiming at the characteristics of the surrounding rock of a gold mine in Kyrgyzstan and the characteristics of ore-bearing production, this paper explores a kind of “Automatic Setting Mining Method for Upright and Broken Orebody (ASMMUBO)”.Then, the corresponding technical difficulties and key technologies are put forward.Finally, the finite element software (FLAC^3D) and the discrete element software (PFC^3D) are used to simulate the collapse of the upper rock mass under the condition of automatic sinking recovery.Through the excavation simulation of four excavations, it is revealed that the rock mass in the upper part of the bracket can automatically collapse and fill the goaf area under the condition of automatic sinking mining, and avoid the empty top operation, which has certain feasibility.
