Problems solved by technology

[0005] Due to the large size of the end-side shearer, the large demand for electricity, and the high price, there are very few coal mines that use the end-side shearer to recover coal from the end-side mine in China, and the development of related technologies is slow

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Coal houses are arranged on the side-wall mining face, and isolated coal pillars of different widths are left between two adjacent coal houses. The continuous mining machine is used for coal room recovery, and the operation is sequential. According to mining requirements, filling mining can be realized, and a filling management system is required to fill the goaf with paste to form an alternate operation of mining and filling.

Abstract

The invention belongs to the technical field of application of coal mining equipment and coal mining methods, and particularly relates to an end slope mining process by using an open-air end slope orecontinuous miner. The end slope mining process comprises the following steps that 101, a mining face is arranged; 102, an equipment mounting and preparation area is arranged; 103, equipment is arranged and mounted; 104, a ventilation system is arranged; and 105, mining is conducted by using the continuous miner. The end slope mining process adopts continuous miner complete set mining equipment, the requirement of mechanized mining of end slope ore is met, the mechanization level of mining of the end slope ore is improved, the production efficiency is greatly improved, the labor intensity of workers is reduced, the stripping volume of rock and soil is reduced, and damage and disturbance to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of the application of coal mining equipment and coal mining methods, in particular to an end-side mining method of continuous coal mining machines in open-pit end-side mines. Background technique [0002] After the open-pit mining is over, the remaining ore remaining around the open-pit boundary is the end-side ore. According to the statistics, the end-side ore accounts for 5% to 16% of the total mining reserves. The end-side coal mining technology is a technology that uses the exposed coal seam of the open-pit coal mine stope to arrange coal mining equipment for raw coal mining, without the need for separate stripping or infrastructure. [0003] Under normal circumstances, after years of open-pit mining in mines, the high and steep slopes that have been formed are in a state of limit equilibrium, and the mining of side-side mines will inevitably affect the safety and stability of the slope. [0004] In for...
