Protective device used for coal mine mining and preventing waste residues from falling

Abstract

The invention discloses a protective device used for coal mine mining and preventing waste residues from falling. The protective device used for coal mine mining and preventing the waste residues fromfalling comprises an air pump and a protective cover, the air pump is mounted in a base block, a banding block is fixed to the output end of the air pump, and the edge end of the banding block is connected with an air bag through a banding line. The air bag is located above the air pump, a fixed disk is mounted at the edge of the air bag, a clamping groove is reserved above the base block, and the fixed disk is mounted in the clamping groove. The protective cover is arranged on the outer side of the air bag, a clamping column and a butting groove are correspondingly formed in the edge sides of the protective cover, and the clamping column is mounted in the adjacent butting groove. A fixed block and a clamping seat are correspondingly mounted at the edges of the top of the protective cover, and the fixed block is connected with the clamping seat through a fixing piece. According to the protective device used for coal mine mining, underground coal mining personnel are conveniently protected, falling of coal residues is prevented from bringing potential safety hazards to the mining personnel, and meanwhile, the trouble of coal mine frame assembly is avoided.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a protection device for coal mine mining that prevents waste slag from falling. Background technique [0002] We have abundant reserves of coal mines, but most of the coal seams in our country are far away from the surface, so open-pit mining cannot be used. For underground mining, it is usually supported while advancing in the coal seam, and there are certain safety hazards in underground coal mine mining. But the current coal mining has the following problems: [0003] (1) During coal mining, with the mining of the coal seam, the waste slag layer at the upper end of the coal seam will leak out, and the falling of the coal slag will bring safety hazards to the miners during mining; [0004] (2) The existing protective device is assembled with a fixed frame. Due to the rigidity of the fixed frame, it is inconvenient to move in the coal mine. At the same time, the assemb...

Problems solved by technology

[0006] The purpose of the present invention is to provide a protection device for coal mine mining that prevents waste slag from falling, so as to solve the problem that the drop of coal slag in existing coal mine mining in the above background technology will bring safety hazards and inconvenience to mining personnel during mining. It is also a troublesome problem to assemble the coal mine frame at the same time.
