Transportation system and transportation method for open-pit mining of ore rocks

Abstract

The invention provides a transportation system and method for open-pit mining of ore rocks. The transportation system comprises a power system and a track system, wherein the track system comprises spliced tracks which are laid on different steps of a stope slope and a dumper which is placed on the tracks; the power system comprises a motor room, a motor driving device which is arranged in the motor room and a traction cable which is connected with the motor driving device and the dumper; the dumper runs along the tracks under the power which is provided by the motor driving device so as to transport mineral aggregates at the bottom of a mine to the ground surface; and the segmented tracks are connected in a hinged mode and can adapt to slopes with different vertical hectare angles, and the environment adaptability of the transportation system is greatly improved. The transportation systems are respectively installed in the east, south, west and north directions of the stope, the transportation position can be adjusted in time along with mining advancing, and the mining progress is accelerated. According to the transportation system, the track transportation system is used for replacing traditional road automobile transportation, so that the waste rock stripping amount during mining is greatly reduced, the mining cost is reduced, automatic transportation is achieved, and the transportation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ore and rock transportation, in particular to a transportation system and method for open-pit mining of ore and rock. Background technique [0002] The technical process of open-pit mining is generally: perforation, blasting, shoveling, transportation and rock removal. The links of each process link, influence and restrict each other, constituting the most basic production cycle of open-pit mining. To extract ore in open pit mines, it is necessary to strip waste rock and mine ore within the boundary grade. The ultimate goal of open-pit mining is to pursue the maximum economic benefit under the given engineering geology and mining conditions. The restriction of economic benefit is reflected in the determination of reasonable slope angle. A large number of studies have shown that if the final slope angle of a large open-pit mine slope is increased by 1°, the amount of rock stripping can be reduced by tens ...

AI Technical Summary

Problems solved by technology

Under certain rock conditions, the slope angle has reached the limit. If the angle is increased, the slope will be unstable and prone to collapse and landslide disasters

At present, when designing an open-pit stope, the pit transportation road will be designed, and the designed road will reduce the slope angle by 2 to 3°, stripping a lot of waste rock, increasing the investment cost, and the fuel consumption is large, polluting the environment, as the mining depth increases increase, the transportation distance increases significantly, and the transportation capacity of the platform is reduced. The applicable economic mining depth is generally 200-300m
