Crushing-loading-conveying integrated coal mining machine and coal mining method thereof

Abstract

The invention discloses a crushing-loading-conveying integrated coal mining machine and a coal mining method thereof. The coal mining machine is mainly used for mining thin and ultrathin coal seams. The coal mining machine comprises a nose, a tail, a cutting device and a conveying device. The nose is connected with the tail through the cutting device and the conveying device. A drive vertical shaft and a motor are disposed on the nose. A driven vertical shaft is disposed on the tail. The drive vertical shaft and the driven vertical shaft are connected through a fixed chain and a transmission chain. A plurality of cutting parts are disposed on the fixed chain. A rack and a plurality of scraper boxes are disposed on the transmission chain. During use, a cutting hole is dug between the upper gate road and the lower gate road of the coal seam, the chains and the chain accessories such as the cutting parts and the scraper boxes are mounted in the cutting hole, during coal mining, the transmission chain drive the cutting parts to cut coal, the cut coal is conveyed to the gate roads through the scraper boxes, and conveyed out through the gate roads. By the coal mining machine, coal crushing, loading and conveying can be achieved automatically, unmanned working face operation is achieved, and high safety degree, low mining cost and high production efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of mining engineering, and in particular relates to a shearer integrated with breaking, loading and transporting and a coal mining method thereof. The coal mining method is mainly used for mining thin and extremely thin coal seams. Background technique [0002] In the underground mining of coal in my country, coal seams with a thickness between 0.8 and 1.3m are thin coal seams, and those less than 0.8m are extremely thin coal seams. Most mines face the problem of mining thin and extremely thin coal seams less than 1m thick. Due to the limited mining height of thin and extremely thin coal seams, the existing mature coal mining methods and mechanical equipment for thick coal seams are difficult to adapt to thin and extremely thin coal seams, which makes the degree of mechanization of such coal seam mining low, and the work of thin and extremely thin coal seams Face ventilation is poor, workers cannot stand in the worki...
