Simulation Study on the Disaster-Causing Mechanism of Geothermal Water in Deep High-Temperature Heat-Damaged Mines

This paper takes the bottom pumping roadway of 33190 machine in No.10 mine China PingMeiShenMa Group as engineering background. is a hydrothermal mine, with strong heat conduction and thermal convection activities between surrounding rock geothermal water. forms anomaly area, making overall temperature field increase affecting environment. According to measured data geological conditions roadway, seepage-heat transfer model constructed using comsol numerical simulation software, emulating effect water upwelling through random cracks at different temperatures pressures, which has an impact on airflow roadway. The study shows that evolution law under pressures roughly same, entrance almost unchanged: heating rate 0, then increases linearly. variation outlet analyzed, both same but pressure, pressure temperature. cooling efficiency are positively correlated, growth correlated pressure; however, far greater than pressure. main influencing factor Therefore, it possible reduce by laying insulation materials plate, evacuating circulating cold-water injection, so improve environment water-heated mines their production efficiency.
