Mining equipment and method for unmanned working face in thin coal seam of short-distance high-gas coal seam group

Abstract

The invention discloses a mining device and a mining method for an unmanned working face of a thin coal seam of a short-distance high-gas coal seam group, and belongs to mining devices and mining methods for the unmanned working face of the thin coal seam. A centralized control center is arranged in an air inlet tunnel of a working face; a main supervising platform utilizes a monitoring and supervising substation to monitor the mining environment, the roof stableness and the coal-bunker bunker location of the working face and the working condition of a device in real time; an electrohydraulic control platform monitors the working condition of a hydraulic supporting frame and realizes machine-following automatic control and control parameter configuration on the basis of the position of a coal mining machine by utilizing a supporting frame infrared sensor; a communication control platform monitors the result of data treatment and analysis on line by utilizing a supervising host; the sequential machine start and stop, the machine-following automatic control and the automatic memory coal cutting control of the working face are completed; the running of the device and the control parameter configuration are automatically controlled; the automatic and unmanned coal mining of the working face of the thin coal seam which are difficultly mined is realized. The control and the monitoring are carried out in the centralized control center in a tunnel; a worker is liberated from the working face of the thin coal seam which is difficultly mined; the labor intensity of the worker is decreased; the production efficiency and the safety status are improved.

Description

technical field [0001] The invention relates to a thin coal seam unmanned working face mining equipment and method, in particular to a thin coal seam unmanned working face mining equipment and method of short-distance high-gas coal seam groups. [0002] The present invention relates to a coal mine mining method, in particular to a method for unmanned working face mining of difficult-to-mining thin coal seams, which is applied to the mining of high-quality coal resources in thin coal seams in the underground mining of coal mines, and the pressure relief and outburst prevention and impact prevention of short-distance high-gas coal seam groups The field of ground pressure prevention and control. Background technique [0003] After years of mining, the reserves of medium-thick and thick coal seams in mines in many areas of my country have been nearly exhausted, while the mining of thin coal seams (thickness ≤ 1.3m) has been in a state of slow development for a long time due to e...
