A return air Shimen coal gangue distribution system

Abstract

The invention belongs to the technical field of coal mining, and particularly relates to an air returning crosscut coal gangue screen and transportation system. The system comprises an air returning crosscut and a concentrated transport roadway, the air returning crosscut is provided with a gangue roadway, an air returning gangue outlet combining roadway is arranged between the air returning crosscut and the concentrated transport roadway, the air returning gangue outlet combining roadway is located at the front section of the gangue roadway, an electric rolling cylinder is arranged in the airreturning gangue outlet roadway, and a gangue screening device cooperating with the electric rolling cylinder is arranged in the air returning crosscut. After a gangue outlet coal discharging systemat the rear route of air returning crosscut excavating is a mining region is improved, one gangue raking machine, one motor vehicle and twenty 1.5t mine trucks are not needed at the discharging port of a gangue chamber of an original air returning crosscut, the level of mechanization is high, the gangue discharging efficiency is high, 50,000 RMB of equipment depreciation expense is reduced, 12 people of labor force input is reduced per day, 540,000 RMB of labor resource cost is reduced, coal mining amount is huge reaching approximately 2,200 tons, 1,100,000 RMB of economical benefits is created, the system is further popularized to be applied to mine shaft roadway excavating, and coal gangue scree and transportation during roadway excavating are achieved.

Description

technical field [0001] The invention belongs to the technical field of coal mine excavation, and in particular relates to a system for distributing and transporting coal and gangue at return air stone gates. Background technique [0002] Excavation is the work of excavating wells, lanes, and chambers of various shapes, sections, or criss-crossing in rock (soil) layers or mine layers. The excavation process is divided into main process and auxiliary process. The main process is to complete the process of ensuring the progress of the working face directly on the working face, as well as the supporting work in the roadway excavation area. The main process is determined by the nature of the rock that the roadway passes through. When excavating hard rock, the main processes include drilling, charging, blasting, ventilation, safety inspection of the working face, rock loading, and roadway support; the basic processes of excavating soft rock include: excavating rock, rock loading...
