The invention discloses a steeply inclined seam dip oblique strike longwall comprehensive mechanical
coal mining method. The method comprises the following steps: preparation: digging a first laneway and a second laneway at the upper end and the lower end of the steeply inclined seam respectively; forming an initial mining working surface with the pitching oblique mining
angle alpha of 25 to 35 degrees between the two laneways; arranging a
coal mining
machine, a scraper plate conveying
machine, and a plurality of hydraulic brackets which are
parallelogram-shaped in the overhead view and form a
supporting system on the initial mining working surface; arranging the
machine head of the scraper plate conveying machine behind relative to the machine
tail while the hydraulic brackets in the propelling direction are sequentially behind a certain distance from the machine
tail of the scraper plate conveying machine; arranging a reversed
loader on the second laneway;
coal mining:
cutting coal up and low by using the coal-mining head of a coal-mining machine; moving the brackets: moving the hydraulic brackets sequentially from bottom to top; pushing and sliding: pushing and sliding by using a scraper trough conveyor of the scraper plate conveying machine in strokes to finish one time pushing and sliding quantity; and transporting coal: transporting coal to the outside by using the reversed
loader. According to the method, the steeply inclined seam comprehensive mining operation is realized conveniently, and
recovery ratio and
resource utilization ratio are increased.
