Combined mine development system based on shaft and packaging tape inclined shaft

Abstract

The invention discloses a combined mine development system based on a shaft and a packaging tape inclined shaft. The combined mine development system comprises an upper main shaft and a lower packaging tape inclined shaft. The main shaft adopts a shaft skip to lift ores, the packaging tape inclined shaft adopts a belt conveyor to lift the ores, and the main shaft is connected with the packaging tape inclined shaft through a transferring station. According to the combined mine development system based on the shaft and the packaging tape inclined shaft, an interior shaft is not needed, the workamount of facilities and the construction difficulty are greatly reduced, wherein the mining depth of the upper main shaft does not exceed 1000m, so that the lifting height of the main shaft is reduced to a reasonable range, and the replacement frequency of a steel rope is reduced; the lower packaging tape inclined shaft is parallel to an ore body, so that the distance from an underground middle haulageway and a linking taxiway to an ore pass fragmenting system is decreased, and the haul distance is shortened; and in short, the development work amount is reduced, and the construction period isshortened.

Description

technical field [0001] The invention relates to the technical field of mine development systems, in particular to a combined mine development system based on vertical shafts and tape inclined shafts. Background technique [0002] With the gradual mining of shallow surface mineral resources, deep mining has become the development trend of future mining technology. Some foreign mines have entered into deep mining, and some domestic mines have entered into or are about to enter into deep mining. There are mainly three types of existing technologies for the development of deep mines: [0003] Technology 1: Adopt a single shaft development form. Such as figure 1 As shown, the main shaft is generally arranged in the footwall of the ore body, and the breakout system is arranged near the main shaft. The ore mined in the underground is transported to the chute in the mining area by the scraper. The ore in the chute in the mining area is slid to the rail transportation level and l...

AI Technical Summary

Problems solved by technology

Since the inclination angle of tape inclined wells is small, generally between 10° and 14°, and the maximum single inclined length of tape inclined shafts is about 1500m, transfer stations need to be arranged between deep well tape inclined shafts. The volume is also very large, especially near the surface. Due to the poor stability of the rock mass, the support is difficult and the construction period is long.
