Laying method of coal working face protection net

Abstract

The invention discloses a laying method of a coal working face protection net, comprising the following steps: 1) extending a steel wire rope from the front end of a bracket telescopic beam, wherein the two ends of the steel wire rope are respectively fixed to the lower side of a machine lane sidewalk, and a shed beam of a lead shed of a wind lane sidewalk, tensioning and straightening the steel wire rope by a chain block, supporting the shed beam fixing the steel wire rope by two single bodies as propping columns, and clamping the two ends of the steel wire rope respectively by rope clamps; 2) firmly connecting the steel wire rope to the protective net, equidistantly spacing several brackets, extending two iron wires from the gap in the middle of the bracket telescopic beam, fixing one ends of the iron wires to the wire rope, and connecting the other ends to the brackets through a prop drawer; 3) advancing a working face, contracting the prop drawer, pulling the wire rope and the metal net sequentially to the bracket telescopic beam, moving the brackets wholly, and after bracket moving, connecting the wire rope and the metal net directly to a bracket top beam. By adoption of the technical scheme of the invention, the safety of coal mining is ensured.

Description

technical field [0001] The invention belongs to the field of coal mining, and more specifically, the invention relates to a method for laying a protective net on a coal mining face. Background technique [0002] In the process of coal mining, some mines have complex geological conditions, short working faces, and frequent installation and retraction of the protective nets on the coal mining face. In this way, the manual directly enters the coal wall and lowers the frame to go online. The support will drop greatly, and the operator directly enters the coal wall. The efficiency of laying is low, and there is a great risk, which may even lead to mining safety accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for laying a protective net on a coal mining face to ensure the safety of coal mine mining. [0004] In order to achieve the above object, the technical solution adopted by the present inventi...
