Abstract

The invention discloses an open-air drilling coal cutter which comprises a power generation set, a movable pump station, a host, a backseat drill pipe warehouse, a telescoping boom auxiliary transport device and a main drill pipe warehouse, wherein the host comprises drill pipe drive motors; the drill pipe drive motors are connected with front transmission cases by drill pipe mechanisms; drill bits are arranged on the front transmission cases; a middle vent pipe is arranged at the drill pipe mechanisms; the backseat drill pipe warehouse is arranged at the tail part of the host; the movable pump station and the main drill pipe warehouse are arranged on the two sides of the host respectively; the movable pump station comprises a high-power motor; an input end of the high-power motor is connected with the power generation set; an output end of the high-power motor is connected with a drive pump by a transfer case; the drive pump is connected with the drill pipe drive motors; and the telescoping boom auxiliary transport device is arranged on the main drill pipe warehouse. The coal cutter solves the problems that the labor intensity of workers is high, the resource recovery rate is lower, and the coal cost per ton is high during side slope coal mining in the open-air coal mine industry.

Description

technical field [0001] The invention relates to a coal mining machine, in particular to a drill type coal mining machine suitable for mining boundary coal in open-pit coal mines. Background technique [0002] In open-pit coal mining, in order to ensure the stability of the slopes of the excavation site and the dump site, construction needs to be carried out according to a certain side slope angle. Since the scope of mining rights is delimited by the surface, when the open-pit coal mine is mined to the boundary, the coal below the step is pressed by the stripping layers at each level of the side wall, which is called the boundary side pressure coal. [0003] At present, there is no very effective method and equipment for coal mining on the boundary slope of open-pit coal mines. The commonly used methods are side-steepening method and step-joining method, which have extremely strict geological requirements for open-pit coal mines, and the workload is heavy. The labor intensit...
