Problems solved by technology

The level of tunneling technology and equipment is directly related to the production capacity of coal mines. High-efficiency tunneling technology and tunneling efficiency are important conditions to ensure efficient mine production. The traditional roadway tunneling and transportation process cannot achieve the purpose of parallel operation, even if parallel operation can be achieved. Operation, that is also laying double tracks, greatly increasing the length of track laying and improving the cost of excavation

Abstract

The invention provides a LongitudinaL shunting structure with a Lifting raiL for roadway construction, and beLongs to the technicaL fieLd of mining engineering. By the adoption of the LongitudinaL shunting structure, the bottom heave phenomenon in current soft rock fLoor roadways is effectiveLy avoided, the roadway construction efficiency is improved, the shunting space is saved, paraLLeL operation of a transporting Link during roadway construction is achieved so that succession of expLoitation can be conducted normaLLy, and the productivity of mines is improved.

Description

technical field [0001] The invention relates to a tunnel excavation longitudinal shunting structure, which belongs to the field of mining engineering. Background technique [0002] Roadway excavation is a frequent and important work in coal mine production. Rock loading and shunting are relatively heavy tasks in excavation. Under normal circumstances, rock loading time accounts for about 35% to 50% of the excavation cycle time. Therefore, improving the comprehensive mechanization level of loading and transportation and its productivity are the main measures to realize rapid excavation. The existing shunting methods in the excavation working face generally have the characteristics of large space occupation, high investment in equipment, and difficulty in moving. In response to these problems, we have made some changes in the transshipment process. The use of longitudinal shunting mine cars for rock slag transfer can greatly improve the tunneling efficiency and save shunting ...
