Underground concentrator maintenance system

Abstract

The invention relates to an underground concentrator maintenance system which comprises a grinding and separating roadway arranged below a mining haulage roadway, wherein a plurality of ore grinding working spans and a plurality of magnetic separation working spans are arranged on the grinding and separating roadway in the length direction; a dehydration working span and the last magnetic separation working span are arranged in parallel; each ore grinding working span and each magnetic separation working span are arranged in a longitudinal linear step manner in the length direction of the grinding and separating roadway according to the working sequence; closed circuit grinding equipment comprising a ball mill-hydrocyclone group is arranged in the ore grinding working spans; a magnetic separator is arranged in the magnetic separation working spans; and the underground concentrator maintenance system is characterized in that a maintenance transitional working span is arranged at the tail part of the last magnetic separation working span and a hoisting shaft system is arranged on one side of the maintenance transitional working span. The underground concentrator maintenance system has the following advantages: all to-be-maintained equipment in a working area can be conveyed to the maintenance transitional working span and a hoisting crown block through a maintenance conveying trolley and is then conveyed to the earth's surface through the hoisting crown block, so that maintenance of an underground concentrator is smoothly and effectively realized.

Description

technical field [0001] The invention belongs to the technical field of maintenance, and in particular relates to a maintenance system for an underground mineral processing plant. Background technique [0002] The ore concentrator is a factory that enriches beneficial metals through crushing, grinding, dressing and other processes of ore mined underground. The current mineral processing plant is built on the surface, and the tailings and waste rocks of the mineral processing are not handled well, which will easily cause environmental pollution, and the accumulation of these mineral processing wastes requires a large amount of land, which is almost impossible to reuse. The beneficiation process of some special metals, such as the beneficiation of gold, requires the use of highly toxic drugs such as cyanide, which causes greater pollution to the environment. Moreover, the mineral processing plant is built on the surface, and the tailings and waste rocks of the mineral processi...

AI Technical Summary

Problems solved by technology

However, a lot of equipment in the underground concentrator needs to be lifted to the surface for maintenance, and the maintenance equipment such as various cranes can only adapt to one width, and can only walk on the track at the same height, which brings difficulties for the equipment maintenance of the underground concentrator difficulty

Finally, because the depth of ore buried underground is as high as hundreds of meters, it is also a difficult problem to lift the equipment that needs to be repaired to the surface.
