Abstract

The application relates to a goaf filling device for underground metal mines, which comprises a sealing baffle and an extension rod. At least one set of clamping seat groups is arranged on the front side of the sealing baffle, each set of clamping seat groups comprises two clamping seat units, the two clamping seat units are symmetrically arranged on the upper part and the lower part of the sealing baffle, and connecting grooves are arranged on the opposite sides of the two clamping seat units respectively. The two ends of the extension rod are inserted into the walls on the two sides of the goaf, and the sealing baffle is installed on the extension rod through the clamping seat units. The goaf filling device for underground metal mines is simple in structure and convenient to erect, can effectively improve the installation efficiency of the sealing baffle, and thus improves the filling efficiency of the goaf. When the filling material solidifies, the sealing baffle and the extension rod can be disassembled for repeated use, which is favorable for reducing the cost of the goaf filling.
