Embodiment Construction

[0053] The technical solution of the present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments of the description:

[0054] Such as figure 1 As shown, the scraper machine 5 is the running track of the coal shearer 7, and the coal shearer 7 reciprocates on the scraper machine 5 to cut the coal seam 3, and the coal lumps fall onto the scraper machine 5 to be transported out of the working face, and the coal mining When cutting, the drum of machine 7 adjusts the mining height according to the coal-rock boundary line 1, and the scraper machine 5 moves the coal shearer 7 in the advancing direction to form a goaf, and at the same time, the oil cylinder at the bottom of the scraper machine 5 pulls the hydraulic support 6 Complete the support of the goaf, reciprocating operation, and complete the mining of coal.

[0055] Such as figure 2 As shown, the inertial navigation device 9 and the explosion-proof box 8 are instal...

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...
