Embodiment 1

[0014] Embodiment 1: The equipment operation cooperation method in the solid filling coal mining face is as follows: the coal cut by the shearer 5 is transported to the coal transport roadway 3 through the scraper conveyor 6 in the coal mining face 1 and transferred to the coal transport The equipment 7 is transported out of the coal mining face 1 by the coal transporting equipment 7; Transferred to the tail 17 of the porous bottom unloading conveyor 12, the gangue is unloaded to the goaf below the porous bottom unloading conveyor 12 through the middle section 16 of the porous bottom unloading conveyor 12 and repeatedly tamped by the compacting mechanism 11.

[0015] exist figure 1 Among them, the coal mining face 1 is covered by the front roof beam of the filling coal mining hydraulic support, the filling face 2 is covered by the back roof beam of the filling coal mining hydraulic support, and the coal transportation lane 3 and gangue transportation lane 4 are set up on the t...

Abstract

The invention provides an equipment matching method for a solid-filling coal face of a coal mine and belongs to coal mining with filling methods. According to the equipment matching method, equipment is composed of a coal cutter, a scraper conveyer, a milling with filling hydraulic support, a coal conveying device, a machine head, a drive motor, a machine head lifting platform, a gangue belt conveyer, a self-moving transfer conveyer, a machine tail, a machine tail lifting platform, a punning mechanism and a conveyer middle section, wherein the coal cutter, the scraper conveyer and the milling with filling hydraulic support are arranged on the coal face; the coal conveying device, the machine head, the drive motor and the machine head lifting platform are arranged in a coal conveying roadway; the gangue belt conveyer, the self-moving transfer conveyer, the machine tail and the machine tail lifting platform are arranged in a gangue conveying roadway; the punning mechanism and the conveyer middle section are arranged in the milling with filling coal face. The conveyer middle section and the punning mechanism are arranged on the rear portion and the bottom of the mining with filling hydraulic support respectively. The self-moving transfer conveyer is in lap joint with the gangue belt conveyer and the machine tail. The machine tail is arranged on the machine tail lifting platform. The machine head and the drive motor are arranged on the machine head lifting platform. A delayed shoring method is used for achieving management of a coal face transition section. By the adoption of the equipment matching method, integrated operation of filling and mining of a comprehensively mechanical solid filling work face is achieved, and the recovery rate of a resource exhaustion type mine is greatly increased.

Description

technical field [0001] The invention relates to a method for matching equipment in a coal mine solid filling coal mining face, in particular to a method for matching equipment in a coal mine solid filling coal mining face. Background technique [0002] Comprehensive mechanized solid material filling coal mining technology is a revolutionary technology of filling mining technology. Since its research and development, this technology has been used in Pingdingshan (under villages), Jining (under dense villages), Yanzhou (under large river embankments) , Wanbei (under the four water bodies), Kailuan (under the railway network) and more than 20 working faces in more than 10 mining areas have been extensively industrialized. This technology is improving the recovery rate of coal resources; using solid materials in the mining area and protecting the mining area Building (structure) structures, land, water body and ecological environment have outstanding technical advantages, and be...
