The invention discloses coal mining equipment comprising a transloading machine, a belt conveyor, a mine roadheader, a conveying belt and a coal slip plate. The transloading machine comprises a self-advancing tail. A transporting belt is arranged on the belt conveyor. The mine roadheader is further arranged below the belt conveyor. The conveying belt is further arranged on the mine roadheader. The front end of the conveying belt is connected with a coal shoveling plate. The rear end of the conveying belt is located on the self-advancing tail. The coal slip plate is obliquely arranged on the self-advancing tail. The upper end of the coal slip plate communicates with the conveying belt. The lower end of the coal slip plate communicates with the transporting belt. The invention further discloses a coal mining method. By arranging the mine roadheader in front of the self-advancing tail, lane bottom coal is recycled; and the recycled lane bottom coal sequentially passes through the conveying belt, the coal slip plate and the transporting belt to be output to a specified position, so that resource waste is reduced, residual coal in a goaf is reduced, and high-temperature spontaneous combustion in the goaf is avoided.
Description
technical field [0001] The invention relates to the technical field of coal mining, in particular to a coal mining equipment and a coal mining method. Background technique [0002] A fully mechanized mining face is basically composed of a shearer, three machines (conveyor, loader, crusher), hydraulic support, shift train (including power supply and distribution, liquid supply, control and other equipment, facilities and devices), belt conveyor machine etc. The side of the fully mechanized mining face close to the belt conveyor or belt conveyor is often called the "head", and the other side is called the "tail". The equipment arranged on the nose side often includes end brackets (generally three), transition brackets (generally two), intermediate frames, scraper conveyor nose, loader, crusher, belt conveyor and shifting train, coal When the machine cuts coal to the machine head side, it completes the cutting, transportation, crushing and reloading of coal through a series o...
