Mine cooling and heat damage utilization system

Abstract

The invention discloses a mine cooling and heat damage utilization system. The system includes a downhole heat damage cooling and heat collection subsystem and an above-well heat damage utilization and heat supply subsystem. The downhole heat damage cooling and heat collection subsystem includes two-phase closed thermosiphon heat collecting and cooling equipment (2), a cold water heat absorbing pipeline (3), a hot water thermal-insulation pipeline (4) and a water inlet pipeline (15). The above-well heat damage utilization and heat supply subsystem includes a heat exchanger (11), a water-sourceheat pump (12), a mine drainage system (13), a heat source utilization module (14), and a water discharge pipeline (16). The system in simple in structure and practical, can well adapt to complex above-well environments and downhole environments of a mine, heat in surrounding rock of a roadway is extracted, thermal damage of surrounding rock is treated, and the environmental temperature in the roadway is effectively reduced; meanwhile heat energy of surrounding rock of the roadway is well utilized, the extracted heat energy is used for heat supplying of builds, water for bathing employees, freeze protection of wellheads and the like in the mine, above-well heat supply and energy consumption are reduced, and the system has huge economic and environment protection value.

Description

technical field [0001] The invention belongs to the technical field of thermal damage cooling and utilization of underground surrounding rocks in coal mines, metal mines and other mines, and specifically refers to a mine cooling and thermal damage utilization system. Background technique [0002] With the increasing demand for mineral resources in my country, the continuous development of deep mining technology, and the increasing mining depth of modern mines such as coal mines and metal mines, the underground temperature is getting higher and higher, which seriously affects the health and safety of underground workers and machinery. The normal operation of electrical equipment, underground high temperature heat damage has become a problem that must be solved in modern mine mining. Practices at home and abroad have proved that for most mines, the ground temperature is the main reason for the formation of mine heat damage, and the impact of ground temperature on the undergroun...

AI Technical Summary

Problems solved by technology

[0003] The traditional method of cooling mine heat damage is to install high-power air-conditioning cooling equipment above and below the mine to cool the air flow entering the roadway. The equipment is complex and consumes a lot of energy, and it does not fundamentally solve the heat damage of the surrounding rock of the mine; at the same time, it does not Effective utilization of the huge geothermal resources contained in mine surrounding rocks and mine water gushing heat hazards, resulting in a large waste of mine geothermal resources
