摘要：

Heat hazard in mine is a problem to be solved urgently because it seriously affects the normal production of mine and the health of workers. This paper puts forward a new method to control seasonal heat hazard of mine by full air cooling system. The system can not only lower temperature and improve environment of mine, but also realize heat supply to meet the antifreezing, bathing requirements for mine and heating requirements for ground buildings. In this paper, taking Jisan coal mine as an example, we introduce the calculation of cooling load and heating load, technical solution, equipment selection, pithead sealing and automatic control technology of full air cooling system. The results show that in summer, after running of the system, inlet air temperature of working face is below 26 degrees C with the average decrease of 3-5 degrees C and relative humidity is 80% with the decrease of 10-15%. In winter, inlet air temperature is 12 degrees C which meets the antifreezing requirements for shaft. At present, cooling system has been put into use in Zhaolou coal mine in Yankuang Group, Jier coal mine, Jisan coal mine and Dongtan coal mine. The operation of the system has played an important role in improving working environment of mine and improving labor productivity.
