Application of High Efficiency Air Cooler for Coal Mining Face in Zhaolou Coal Mine

The refrigeration and cooling is an effective measure to prevent and control the high temperature of the mine, which is an important cooling equipment. According to the characteristics of the underground hydraulic support, the air cooler is designed in a semi-open mode when refrigeration and cooling is carried out in working face of Zhaolou Coal Mine to make it meet the needs of underground cooling and move forward with the hydraulic support to avoid the repeated disassembly work. According to the calculation, the optimal placement position of the combined work of the air cooler is calculated to meet the refrigeration and cooling demand of the long-distance and large width working face.
