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

Abstract

The present disclosure proposes a coal mining system and a mining method for self-forming lanes without coal pillars. The coal mining system includes a coal mining mechanism, and the coal mining mechanism includes a first scraper conveyor and a first coal mining machine. The coal mining system also includes the headway forming mechanism, transfer machine and conveyor. The machine head roadway forming mechanism includes the second scraper conveyor and the second shearer. The second scraper conveyor is arranged on one side of the head of the first scraper conveyor along a second direction and extends forward, and the second direction is perpendicular to the first direction. The second shearer is movably arranged on the second scraper conveyor. The transfer machine is arranged on the head side of the first scraper conveyor, and the first scraper conveyor and the second scraper conveyor are respectively connected to the transfer machine. The conveyor is arranged along the second direction and connected to the transfer machine. The coal mining system can advance toward the working face along the second direction, and the second coal mining machine can mine the part of the working face on the side of the machine head when the coal mining system is advancing, and form the machine head retaining roadway in combination with top cutting and pressure relief Shun trough.

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...
