Abstract

The invention discloses a mining coal machine, in particular a coal drilling machine suitable for mining a thin coal seam, which comprises a main frame, an electric control system (12), a hydraulic system (9), a drilling tool and an auxiliary system (8), wherein one or two sides of the main frame are provided with a four-shaft linkage drilling tool; the drilling tool consists of a drilling rod (29), an air pipe (16), a front transmission gear box (15) with four output shafts and a drilling bit (14); power is transmitted to the drilling bit (14) through the drilling rod (29) and the front transmission gear box (15); and the air pipe (16) is communicated to the drilling bit (14) end. The invention also discloses a coal drilling machine of which the two sides of the main frame are provided with drilling tools. When used for thin and ultrathin coal seam mining, the coal drilling machine realizes an unmanned working face mining mode with convenient and safe operation, and solves the problems that the mining method of conventional equipment cannot mine or can mine but has low efficiency, high cost, bad reliability and poor safety, which is ideal equipment for safe and efficient mining of the thin and ultrathin coal seam.

Description

technical field [0001] The patent of the present invention relates to a brand-new coal mining machine for coal mines, especially a four-axis linkage type bi-directional high-efficiency coal drilling machine for thin coal seams or extremely thin coal seams to realize coal mining in unmanned working faces. , Coal mining in coal seams with gas and coal dust explosion hazards. Background technique [0002] At present, most of the mechanized coal mining methods at home and abroad are carried out on the mining face with a length of 120 meters to 300 meters, which is composed of coal mining machinery, transportation machinery, roof support and goaf treatment, namely So-called longwall coal mining. The coal falling equipment of this method is mainly drum shearer and coal plow. The whole coal mining system is relatively complicated, and there are many equipment and workers used. This coal mining method has the problems of high cost, difficult management and poor safety. Especially ...
