Abstract
According to less study on the geothermal disaster control technology of the construction mine and the geothermal control complicated status, based on the mine geothermal disaster features of high environment temperature of the mine roadway heading face, high loading of temperature reducing;high cooling lost of the ventilation supply along the routing, thermal and moisture change insufficient between the low moisture air and the roadway heading face and the low utilization rate of t he temperature cooling equipment in the construction mine, a comprehensive control measures combined with the non-mechanical refrigeration and mechanical refriger ation were designed for the temperature cooling of the construction mine.The non-mechanical refrigeration method would include a ventilation volume increased, a ratio nal ventilation mode selected, double roadways heading, ventilation with double insolated air ducts, thermal sources control, management enhanced and others.When t he non-mechanical cooling method could not meet the requirements of the temperature cooling, the mechanical temperature cooling method would be applied.An analys is was conducted on Zhaolou construction mine as example.The analysis showed that the operation effect of the mechanical cooling system was good and the temperat ure of the roadway heading face in the underground mine could meet the requirements of Mine Safety Regulations.
