Middle single-drum short machine body thin seam coal mining machine and mining method thereof

Abstract

The invention discloses a middle single-drum short machine body thin seam coal mining machine and a mining method thereof. The coal mining machine comprises a coal mining machine body, a cutting drum and coal loading mechanisms, and the cutting drum is arranged on the middle portion of the coal mining machine body. The coal loading mechanisms are arranged at the two ends of the coal mining machine body. The mining method comprises the following steps that (1) the coal mining machine advances directly from a haulage way on the lower portion of a working face; and (2) the coal mining machine moves upwards, coal is cut by the cutting drum on the middle portion, an arc-shaped coal loading plate on the rear portion is in a movable coal loading state for coal loading, the arc-shaped coal loading plate is behind the coal mining machine by a certain distance for advancing a powered support, and the arc-shaped coal loading plate is behind the powered support by a certain distance for pushing. According to the middle single-drum short machine body thin seam coal mining machine and the mining method thereof, the coal loading mechanisms are arranged at the two ends of the coal mining machine, the coal loading effect of the coal mining machine can be greatly improved, the labor intensity of workers of a thin coal seam face is relieved, and the production safety is improved; and due to the facts that the machine body is short, and the cutting drum is located in the middle of the coal mining machine body, the coal mining machine can directly advance from the haulage way and a tailgate of the working face, the circulation operation time can be shortened, and the production efficiency of the working face is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a coal shearer and a mining method. Background technique [0002] my country's thin coal seam resource reserves are abundant, and the recoverable reserves account for about 20% of the total recoverable reserves. However, the annual output of thin coal seams only accounts for 10.4% of the country's total output, and most of them are based on backward mining techniques such as blast mining and ordinary mechanization. Compared with the high-yield and high-efficiency mining of medium-thick coal seams, the mining of thin coal seams in my country has long been in the dilemma of high labor intensity, low degree of mechanization, poor safety conditions, and low economic benefits. The development of high-efficiency mechanized mining technology is a key technical problem that needs to be solved urgently in thin coal seam mining . [0003] At present, the commonly used thin coal seam me...
