A system and method for unmanned mining of coal mines

Abstract

The invention discloses a coal mine unmanned mining system and method. The coal mine unmanned mining system comprises a coal mining machine, a main control computer, a patrol robot, a hydraulic support electrohydraulic control system, a remote control console and a coal wall video camera, wherein the main control computer is electrically connected with the patrol robot and the coal wall video camera; the main control computer is electrically connected with the coal mining machine through the remote control console; and the main control computer is electrically connected with the hydraulic support electrohydraulic control system. The coal mine unmanned mining system and method solve the problem that automated mining systems for thin seams are poor in adaptability to coal seams of other thickness; and by applying an inspection robot technology to mining of a fully mechanized coal face, the coal mine unmanned mining system and method also solve the problems that conventional mine automation production fails to adapt to geological condition changes and must be interfered by manpower. The coal mine unmanned mining system and method intelligently correct automatic mining of the fully mechanized coal face through various sensing methods.

Description

technical field [0001] The invention relates to a coal mine mining system and method, in particular to an unmanned mining system that uses a variety of monitoring equipment to maintain automatic production of coal mine working faces. Background technique [0002] As the demand for safe and efficient production in coal mines is getting higher and higher, how to realize coal mines through automation and intelligent technology has also attracted more and more attention from coal mining enterprises and equipment manufacturers. The application of fully mechanized mining equipment automation, intelligent control technology and related equipment is an important way to improve the efficiency and safety of coal mining. An important indicator of whether mining equipment is advanced. Traditional coal mining is mainly based on mechanical equipment, emphasizing the physical properties of equipment. With the popularization of fully mechanized mining automation in coal mines, independent...

Problems solved by technology

[0004] In the prior art, the automatic mining systems for coal mine working faces disclosed in CN202510120U and CN102337891A are all applied to thin coal seams, and thin coal seams refer to coal seam conditions with a thickness of 0.8 meters to 1.3 meters. It is simple, with small changes and fluctuations. Mining can be realized by using simple shearers, automation of supports and manual intervention. When it is applied to other common coal seams, due to the complex geological conditions of the working face, the inclination angle of the working face fluctuates greatly. The change of coal seam is also large, which will cause various problems such as the decline of coal quality in the mining face, uncontrollable straightness, and reduced equipment life. At the same time, due to the small space of thin coal seam, the installation of video system reaches a certain density to achieve no blind area coverage , but medium-thick coal seams require a substantial increase in the scope of video observation, and ordinary fixed video systems cannot achieve full coverage, resulting in no basis for manual remote operation
