Quick tunnelling and gangue transportation system for coal mine

Abstract

The invention discloses a quick tunnelling and gangue transportation system for a coal mine. The system comprises a tunnelling machine used for operating on a tunnelling working surface, an original gangue storage cabin used for storing a preset quantity of gangues, an original transportation belt used for transporting the gangues mined by the tunnelling machine to the original gangue storage cabin, a coal storage cabin used for storing coal ores, an expanded gangue storage cabin arranged in the coal storage cabin for temporarily storing the preset quantity of gangues, and an expanded transportation belt used for transporting the gangues mined by the tunnelling machine to the expanded gangue storage cabin. The system disclosed by the invention can simultaneously start the original transportation belt and the expanded transportation belt to transport the gangues in two paths, an original gangue discharging way and a temporary gangue discharging way are combined, the original gangue storage cabin and the expanded gangue storage cabin arranged in the coal storage cabin can be simultaneously used for temporarily storing and buffering the transported gangues, gangues accumulated on thetunnelling working surface can be quickly cleaned and carried away, a parallel operation of tunnelling and gangue discharging is realized, a centralized continuous gangue discharging effect is achieved, a gangue transportation speed is quickened, and a tunnel tunnelling speed is obviously improved.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a gangue transportation system for fast driving in coal mines. Background technique [0002] At present, the loading and transportation of gangue is the heaviest and most labor-intensive during the excavation of coal mine roadways in my country, and generally accounts for 35% to 50% of the excavation cycle time. This process has many links and many labors, which is not only inefficient, but also greatly increases the probability of transportation accidents during excavation, which has seriously restricted the process of mine production centralization, mining mechanization and mine large-scale. [0003] During the preparation process of the gas mine mining area, due to the needs of the gas control project, many rock roadways were designed and constructed. The gas control pattern of roadway (mechanical, medium coal, wind roadway)", that is, the use of low-level drainage r...

AI Technical Summary

Problems solved by technology

At this time, a large amount of gangue that is too late to be transported is often accumulated at the excavation face, and the gangue storage bin is full of gangue, and most of the remaining gangue is difficult to quickly clean up, resulting in the excavation face having to be shut down to wait for the transportation and cleaning of excess gangue. The operation cannot be carried out stably and continuously, and the excavation efficiency is low

Moreover, in the prior art, transport vehicles and other equipment are generally used to transport the gangue at the excavation face to the gangue storage bin for storage, the transportation capacity is limited, and the transportation efficiency is low, and the transportation line is prone to blockage, resulting in the problem of difficult extraction of gangue , limiting the construction speed of each rock roadway
