Embodiment 1

[0026] Such as figure 1 Shown in the figure is an ore lifting method in an underground mine. The ore mined by crushing underground is shoveled and transported to a mine bin or a storage chute to be processed in the next process. The crushed ore is ground underground, and then screened after grinding. The ore with a suitable particle size enters the pulping process, and the unqualified ore returns to the grinding process. The qualified ore after grinding is pulped underground, and the ore slurry produced is stored in the underground slurry storage tank, and then the ore slurry is pumped to the surface through the slurry pipeline and slurry pump. The water used for pulping is the underground drainage of the mine, that is, the surface water that needs to be pumped and discharged from the underground. In the pumping process, water is used as a carrier to pump the prepared slurry to the surface. The filtered drainage of the surface pulp is used for ore pulping. After the pulp is ...

Embodiment 2

[0028] Such as figure 2 Shown in the figure is an ore lifting method in an underground mine. The ore mined by crushing underground is shoveled and transported to a mine bin or a storage chute to be processed in the next process. The ore after pulp crushing is ground underground, and the grinding is autogenous or semi-autogenous. After grinding, the ore is screened, and the ore with a suitable particle size enters the pulping process, and the unqualified ore returns to the grinding process. The qualified ore after grinding is pulped underground, and the ore slurry produced is stored in the underground slurry storage tank, and then the ore slurry is pumped to the surface through the slurry pipeline and slurry pump. The water used for pulping is the underground drainage of the mine, that is, the surface water that needs to be pumped and discharged from the underground. In the pumping process, water is used as a carrier to pump the prepared slurry to the surface. The filtered ...

Abstract

The invention discloses an underground mine and ore lifting method. The underground mine and ore lifting method comprises the following steps: step (1) crushing mined ores underground; step (2) grinding the ores crushed in the step (1) underground; step (3) preparing the ores ground in the step (2) underground into slurry; and step (4) pumping the ore slurry in the step (3) to the ground by a slurry conveying pipeline. Compared with a traditional lifting method, the underground mine and ore lifting method has the advantages of transportation cost conservation, zero pollution to the environment, high transportation efficiency, great conveying capability and the like.

Description

technical field [0001] The invention relates to the technical field of ore lifting in underground mines, in particular to large-scale underground mines with large underground water inflows. Background technique [0002] At present, the ore lifting methods in underground mines mainly use cage lifting, skip lifting, belt conveyor lifting or trackless equipment to reach the surface. These traditional lifting methods are widely used in the current underground ore mining. However, the above-mentioned lifting methods all have defects such as large safety hazards, serious environmental pollution, high transportation costs, and inability to continue production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ore lifting method in an underground mine, which can have the advantages of saving transportation costs, zero environmental pollution, high transportation efficiency and large transportation capacity compared with...
