Problems solved by technology

However, the width of the shaft of the gangue inclined shaft is about 3.2m. After the belt is laid in the shaft, the remaining space is small. When the staff cleans up the coal and slag on the bottom of the shaft, the risk factor is high, the cleaning is difficult, time-consuming and labor-intensive , and the cleaning effect is not ideal

Abstract

The embodiment of the invention discloses a roadway cleaning method. The roadway cleaning method includes the steps that a dredging connection roadway is formed by construction in the direction perpendicular to the extending direction of a slag outlet roadway at the tail of a belt conveyor of the slag outlet roadway; a chute is formed by construction at a bottom plate of the dredging connection roadway to enable slag to enter the chute; the slag in the chute is conveyed to the belt conveyor. By means of the roadway cleaning method, cleaning space can be enlarged, the cleaning difficulty is lowered, the cleaning safety coefficient is increased, mechanical cleaning can be achieved, and cleaning efficiency and the cleaning effect are improved.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a roadway cleaning method. Background technique [0002] Maiduoshan Coal Mine is a mine with extremely complex hydrology. During the excavation of the roadway, there is a lot of water splashing and local water gushing. During the process of slag extraction, mine water and coal gangue are mixed together and transported outward through the gangue inclined shaft. Because the shaft slope of the gangue inclined shaft is relatively large, about 20°, coal and slag are seriously scattered along the gangue inclined shaft, especially within 1000m from the slope change point at the bottom of the gangue inclined shaft. The nearest slope change point at the bottom of the inclined shaft. The slope point refers to the intersection point of two adjacent slope lines on the longitudinal section of the route, and the longitudinal section is parallel to the length direction of the route. Howeve...
