Abstract

The invention discloses an energy-saving method and system for underground mine double-slurry inputting and discharging. Energy of underground slurry transferred from the earth's surface serves as main power which is used for raising underground slurry to be discharged to the earth's surface. By the aid of the method and the system, the energy is saved, and production costs for ventilation, temperature reduction, pipeline abrasion and the like are reduced.

Description

[0001] technical field [0002] The invention relates to a method for conveying slurry in underground mines, in particular to an energy-saving method for double slurry input and discharge in underground mines. The invention also relates to a system implementing said method. Background technique [0003] Due to the increasing emphasis on environmental protection and mining safety requirements, underground mines are now vigorously promoted for filling mining. Paste filling relies on pump pressure, which is expensive, but it separates less water in the downhole, and the slurry has less wear on the pipeline; most other filling methods rely on self-flow, and more water is separated in the downhole , Due to the high flow rate of the slurry, the slurry wears heavily on the pipeline. In addition to the wear, it converts most of the potential energy into heat energy, which is not conducive to underground operations, and also increases the cost of ventilation and cooling. The vas...
