Problems solved by technology
However, the former has the problem of low utilization rate of equipment, while the latter has problems such as high operating cost, low coefficient of refrigeration performance, and attenuation of cooling capacity in addition to low equipment utilization rate.
[0005] It can be seen that the energy demand of coal mines is huge, and various energy supply equipment are needed to supply energy. However, the energy utilization rate of energy supply equipment is low, and the waste heat resources are abundant. At present, there are generally problems such as insufficient use of waste heat and waste of resources.

Description
technical field [0001] The invention relates to the technical field of heat energy utilization of multiple heat sources in coal mines, in particular to a system for comprehensively utilizing waste heat in coal mines. Background technique [0002] The mining area has year-round needs for electric energy, hot water for bathing, and hanging basket drying. In summer, there is demand for well cooling and building cooling. In winter, there is demand for well shaft antifreeze and building heating. [0003] Coal-fired boilers, gas-fired boilers or electric boilers are mostly used for hot water for bathing, basket drying, well shaft antifreeze in winter, and building heating. However, coal-fired boilers have problems such as low thermal efficiency, pollution of the environment by flue gas, and waste of resources. Gas-fired boilers have problems such as high nitrogen oxide emissions, high operating costs, and unstable natural gas supply. Electric boilers have the problem of high oper...
