Abstract

The invention relates to a high-dipping low seam self-walking simple drill coal mining machine and a mining method thereof, which belongs to the drill coal mining machine and mining method. The simple drill coal mining machine comprises a host, a control board, a pumping station, a caterpillar base plate, a support hydraulic column, a pedestal, a stable hydraulic support, a drilling tool assembly and a coal baffle plate. A drilling rod and a drilling rod in the drilling tool assembly are connected through a planetary gear decelerator, the coal baffle plate employs a full transparent design; the invention provides a high-dipping low seam mining method, the height of the support hydraulic column is adjusted to determine the drilling direction, coal mined under gravity effect falls to a scraper plate conveyer along a drill pit, a goaf employs a nature caving method for treatment, and the ventilation mode of a drilling surface is a U type ventilation mode. According to the invention, jamming of a drilling tool can be effectively solved, drilling power and coal breaking effect of the drill coal mining machine can be ensured, and the drill coal mining machine has the advantages of simple production process, low equipment cost of working surface and high technical economic benefit, and the drill coal mining machine has important meaning for increasing coal mining rate and prolong the service time limit.

Description

technical field [0001] The invention relates to a coal drilling machine and a mining method, in particular to a self-propelled simple coal drilling machine and a mining method for steeply inclined thin coal seams. Background technique [0002] In recent years, most mines in my country have entered the later period of service life. In order to extend the service life, they choose to mine steeply inclined thin coal seams. The occurrence conditions of steeply inclined thin coal seams are complex, with the characteristics of high difficulty in mining, low recovery rate of coal resources, and large consumption of mining resources. Traditional mining methods are complex in process, low in mining efficiency, and require high equipment and technology, so it is difficult to achieve good technical and economic results. . Contents of the invention [0003] The purpose of the present invention is to provide a self-propelled simple drilling and shearing machine and mining method for s...
