A Mine Heat Hazard Control and Comprehensive Utilization System

Abstract

The invention discloses a mine heat damage control and comprehensive utilization system, which includes a filling body arranged on the inner wall of the mine roadway, an underground heat exchange subsystem and an aboveground heat energy circulation subsystem. The underground heat exchange subsystem includes an underground reservoir located in the goaf group, water separator, multiple heat exchange tubes, water collectors and thermal insulation and heat transfer tubes, multiple heat exchange tubes are buried inside the filling body along the roadway, and the underground reservoir group passes through the water separator and the water inlet end of multiple heat exchange tubes The water outlets of multiple heat exchange tubes are connected to the thermal insulation and heat transfer tubes through the water collector; the ground thermal energy circulation subsystem includes a circulation pump, a heat pump, a heat supply end and a surface reservoir, and the thermal insulation and heat transfer tubes are connected to the circulation pump, and the circulation pump It is connected with the heat pump, and the heat pump is connected with the heat supply end, and the heat supply end provides heat for users. The mine heat damage treatment and comprehensive utilization system provided by the invention has simple structure, low operating cost, absorbs deep geothermal energy, realizes cooling, converts heat damage into usable energy, turns waste into treasure, and is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of mine cooling, in particular to a mine heat damage control and comprehensive utilization system. Background technique [0002] my country is a large coal-producing country in the world, and it is also the country with the most high-temperature heat-damaged mines. With the increase of mine mining depth, the problem of mine high temperature heat damage is becoming more and more serious. Underground high temperature and high humidity climate conditions not only damage the health of workers, but also greatly reduce labor productivity, and even make mining work impossible. [0003] At present, mine cooling methods are divided into two types: non-refrigeration cooling method and refrigeration cooling method, including ventilation cooling, heat source reduction, ice cooling cooling, etc., and the two methods are often combined for cooling practice. For mines with serious heat damage problems, refrigeration cool...

AI Technical Summary

Problems solved by technology

For mines with serious heat damage problems, cooling is mainly used to cool down, supplemented by non-refrigerating cooling. This cooling method is generally applicable and has good results, but it is not economical and energy-saving.

Moreover, the ventilation and cooling of the mining operation site in the mine is realized through high-power air-conditioning equipment, but this kind of high-power air-conditioning equipment is bulky, difficult to maintain, and the investment cost is extremely high. At the same time, due to its large power consumption, the operating cost also higher
