Description

technical field [0001] The invention relates to a simulation test method for heat and moisture exchange in deep mining of mines, which is especially suitable for the research on heat damage control technology faced by deep mining of metal mines, and provides on-site environmental simulation for studying the heat-moisture exchange of air in single-headed roadways. The theoretical calculation value can be verified by laboratory simulation. Background technique [0002] With the reduction of shallow resources, the mining capacity continues to increase, and the mining depth also continues to increase. Mining deep resources has become the main method of mining, while deep mining will inevitably face the problem of high temperature and heat damage in deep wells. The increase in geothermal heat has become a constraint. One of the bottlenecks of safe production, high yield and high efficiency, and harmonious development of mines. Heat damage problems such as high temperature and hi...
