Example Embodiment

[0025] Example 1

[0026] Such as figure 1 As shown, an underground mine ore hoisting method is to crush the mined ore underground, and then shovel and transport it to a ore warehouse or a mine chute for processing in the next process. The ore crushed by the slurry 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. After grinding, qualified ore is pulped underground, and the resulting ore slurry is stored in the underground slurry 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 the carrier to pump the prepared slurry to the surface. The filtered drainage of ground pulp is used for ore pulping. After the pul...

[0027] Example 2

[0028] Such as figure 2 As shown, an underground mine ore hoisting method is to crush the mined ore underground, and then shovel and transport it to a ore warehouse or a mine chute for processing in the next process. The crushed ore is ground underground, and the grinding is self-grinding or semi-self-grinding. After grinding, the ore is screened and processed, and the ore with a suitable particle size enters the pulping process, and the unqualified ore returns to the grinding process. After grinding, qualified ore is pulped underground, and the resulting ore slurry is stored in the underground slurry 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 the carrier to pump the prepared slurry to the surface. The filt...

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...
