Medium-thickness inclined coal seam fully mechanized coal mining face inclined adjustment control method

Abstract

The invention provides a medium-thickness inclined coal seam fully mechanized coal mining face inclined adjustment control method. An inclined fully mechanized coal mining face is manually formed through cutter increased or reduced mining; a scraper conveyor is in a balanced state without moving up and sliding down through an inclined adjustment pushing movable frame; and in order to maintain thestate, mining by a coal cutter increased or reduced fully mechanized coal mining face and the movable frame, pushing of the scraper conveyor and related operations under special conditions are specified, so that the frequent problems of moving up and sliding down of the scraper conveyor are effectively solved. The phenomenon of unsmooth coal piling or safety channels caused by irrationality of thescraper conveyor and transfer machine joint relation and the equipment and end roadway space relation due to frequent problems of moving up and sliding down of the scraper conveyor is prevented. Meanwhile, the phenomenon of engagement, extrusion, tilting or collapse of hydraulic brackets of the fully mechanized coal mining face is prevented; and the production efficiency of the fully mechanized coal mining face and the safe production standardization level are improved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to an inclination control method for fully mechanized mining working faces in medium-thick inclined coal seams. Background technique [0002] At present, the inclination angle of the medium-thick inclined coal seam (the coal seam with an inclination angle of 25° to 45° during underground mining) is relatively large, and the scraper conveyor on the fully mechanized mining face often appears to go up and down, resulting in the overlapping relationship between the scraper conveyor and the transfer machine, and the equipment The unreasonable spatial relationship with the end roadway will cause coal piles or unsmooth safety passages; at the same time, it will also cause the hydraulic supports of the fully mechanized mining face to bite, squeeze, crooked or even collapse, thus posing a threat to safe, high-quality and efficient production . Contents of the invention [0003] In view of the a...
