Method for Raising Gangue in Main Shaft of Coal Mine

Abstract

The invention discloses a method for lifting gangue in a coal mine main shaft. The method comprises the following steps of: reforming the conventional mining area yard till the conventional mining area yard is suitable for running of a 3-ton drop-bottom car; transporting gangue: loading gangue produced by using each drilling head into the 3-ton drop-bottom car by using a rake loading machine, transporting to the mining area yard, lifting to a main haulage roadway through a mining area winch, centralizing to the amount of one train in the main haulage roadway, and towing to a reformed 3-ton drop-bottom car unloading station by using a power locomotive for unloading and storing; and transporting to a main shaft swinging bucket in an idle main shaft coal lifting state, lifting onto the ground through the main shaft, and transporting to a coal gangue brick factory by using a ground special belt conveyer. Due to the adoption of the method, direct entrance of the 3-ton drop-bottom car into a tunneling working surface for transporting gangue is realized, underground transporting times and narrow gage vehicle transportation frequency are lowered, the loading and transportation efficiency is increased, and a foundation is laid for quick elimination of 1-ton mine cars.

Description

technical field [0001] The invention relates to coal mine lifting transportation technology. Background technique [0002] The gangue produced underground in coal mines is not only crushed underground to fill goafs, but also brought up to the ground for making gangue bricks. The traditional transportation and lifting method is that the waste rock produced by each excavation head-on is loaded into a 1-ton fixed mine car with a dumper, transported to the mining area depot, and then lifted to the transportation road by the mining area winch, where it is concentrated into a train After the number of vehicles is reached, the auxiliary shaft yard is towed by a power locomotive, and then the 1-ton mine car is transported to the ground through the auxiliary shaft cage. When the auxiliary shaft is lifted, the following intermediate transfer links are required, bottom trolley → layer change and tank filling → hoist lifting → wellhead cart → layer change and tank discharge → high-leve...
