The invention discloses a heat and humidity exchange simulation testing system for a non-coal solid mine deep mining excavation tunnel. A simulated tunnel is a rectangular grotto obtained through being scaled down according to a field practical blind excavation tunnel, the upper side, the lower side, the left side, the right side and one end of the rectangular grotto are sealed, a tunnel heat source simulation device consists of an electric heating film (5) and a heating control device (10), an in-tunnel humidity environment simulation device is formed by connecting a humidifier pipe (6) with a humidifier (11), an in-tunnel fresh air quality simulation device is formed by sequentially connecting a fan (12), a humidifier (11'), an electric heater (14) and a fresh air pipe (16), and a tunnel temperature reduction refrigeration simulation device consists of a refrigeration machine set (1), an air cooler (4) and a cold air pipe (15). The heat and humidity exchange simulation testing system has the advantages that the field real heat and humidity exchange environment is provided for researching heat and humidity exchange of air in the blind tunnel, the field simulation verification in a laboratory is realized on theoretical calculation results, and good practical significance popularization and application values are realized for solving the heat damage problem of the existing deep well mining.

Description

technical field [0001] The invention relates to a heat and humidity exchange simulation test system for deep mining of non-coal solid mines, which is especially suitable for the research on heat damage control technology faced by deep mining of metal mines, and provides an on-site environment for studying the heat-moisture exchange of air in single-ended roadways Simultaneously, 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 te...
