Problems solved by technology
[0002] At present, the country is vigorously promoting the intelligent and unmanned coal mining face, but due to the cumbersome circuit system of the coal shearer and the straight-line coal cutting of the coal shearer, a single point of failure requires a complete shutdown of the working face for manual switching. This has greatly hindered the promotion of intelligent unmanned working faces; at the same time, the severe vibration of the shearer during operation caused a large area of the coal wall in front, artificially damaging the load-bearing structure of the roof, which is not good for the roadway support

Description
technical field [0001] The invention relates to the technical field of coal mining systems, in particular to a hook machine applied to the N00 construction method and a coal mining system using the hook machine. Background technique [0002] At present, the country is vigorously promoting the intelligent and unmanned coal mining face, but due to the cumbersome circuit system of the coal shearer and the straight-line coal cutting of the coal shearer, a single point of failure requires a complete shutdown of the working face for manual switching. This has greatly hindered the promotion of intelligent unmanned working faces; at the same time, the severe vibration of the shearer during operation caused a large area of the coal wall in front, artificially damaging the load-bearing structure of the roof, which is not good for the roadway support . Contents of the invention [0003] A main purpose of the present invention is to overcome at least one defect of the above-mention...
