Coal mining system and no-pillar self-forming lane mining method based on coal mining system

Abstract

The invention discloses a coal mining system and a no-pillar self-forming lane mining method. The coal mining system comprises a coal mining mechanism, the coal mining mechanism comprises a first scraping plate conveyor and a first coal mining machine, the coal mining system further comprises a machine head lane forming mechanism, a reversed loader and a conveyor, the machine head lane forming mechanism comprises a second scraping plate conveyor and a second coal mining machine, the second scraping plate conveyor is mounted on one side of a machine head of the first scraping plate conveyor inthe second direction and extends forwards, the second direction is perpendicular to the first direction, the second coal mining machine is movably mounted on the second scraping plate conveyor, the reversed loader is mounted on one side of the machine head of the first scraping plate conveyor, the first scraping plate conveyor and the second scraping plate conveyor are connected to the reversed loader, the conveyor is mounted in the second direction and is connected to the reversed loader, the coal mining system carries out propelling towards a work face in the second direction, the second coal mining machine carries out mining on the part, located on one side of the machine head, of the work face when the coal mining system carries out propelling, and in combination with top cutting pressure relief, a machine head reserved lane crossheading is formed.

Description

technical field [0001] The present disclosure relates to the technical field of mining, and in particular, to a coal mining system and a mining method based on the coal mining system for self-forming lanes without coal pillars. Background technique [0002] Constrained by the major defects of traditional coal mining methods (such as the 121 construction method), that is, the huge resource loss caused by leaving coal pillars, the complexity of the coal mining system caused by numerous roadways, and the tension in mining continuity caused by mining separation, Academician He Manchao The N00 mining method without coal pillars was creatively proposed, which truly realized the mining without coal pillars, optimized the roadway layout system, and eliminated the tension of mining succession. According to the N00 construction method of longwall mining, the current N00 construction method roadway layout system is as follows figure 1 As shown, three roadways need to be prepared befor...

AI Technical Summary

Problems solved by technology

[0004] In the current working face equipment layout system, a transfer machine is arranged at the head of the working face. direction) is connected with the belt conveyor, and the scraper conveyor-reloader-belt conveyor together constitute the coal logistics system of the working face. The coal machine is installed on the scraper conveyor, so the coal shearer cannot surpass the transfer machine to cut coal, and it is difficult for the coal shearer to cut coal across the machine head
