Fully mechanized coal mining face coal rock identification device and method

Abstract

The invention discloses a fully mechanized coal mining face coal rock identification device and method. According to the device, an embedded industrial personal computer is used as a data processing platform, coal mining machine controller software, a coal mining machine positioning system and a coal rock identification system are fused, and thus a comprehensive working face coal rock identification system is established. By applying the system, the working precision of a coal mining machine is improved, a measuring track is provided for cutting of the coal mining machine on a fully mechanizedcoal mining face, the problem that the cutting height of a roller cannot be adaptively adjusted when the coal mining machine works is solved, control over the coal mining machine is changed into closed-loop control from open-loop control, and the coal mining efficiency and reliability of the coal mining machine are improved.

Description

technical field [0001] The invention relates to a coal rock identification device and method in a fully mechanized mining face, belonging to the field of intelligent coal mining. Background technique [0002] Accurate identification of the boundary line of the coal seam roof is the key technology to realize the intelligent working face and unmanned working face. [0003] At present, when the shearer is working, it mainly relies on the vision and hearing of the driver to adjust the height of the cutting drum of the shearer. Due to the high concentration of dust and water mist in the mine and the serious noise pollution, the driver of the shearer cannot control the vibration of the shearer. The boom cannot be adjusted accurately, resulting in under-dug or over-dug situations, resulting in waste of resources and certain safety hazards. Due to the complex geological conditions and various types of coal and rock in my country, it is difficult to promote foreign mature technologies...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problem that the height cannot be adjusted adaptively during the cutting process of the fully mechanized mining face, the present invention proposes a coal-rock identification device for the fully mechanized mining face, so as to realize the identification of the coal-rock boundary line of the working face, and can be used for mining The coal machine provides automatic height adjustment data, which provides a basis for the adjustment of the traction speed of the coal shearer and the cutting speed of the drum
