Abstract

For underground mine coal thermal environment and coal temperature parameters of heat hazard mine,this paper analyzed the causes of heat hazard in mine.According to the specific conditions of Jining No.3 coal mine,heat hazard management programme in drivage face was making.Utilizing local low-temperature water from cooling system,lower the heat of airflow,the paper introduced the system working principle,layout and operation processes,and analyzes the effect of deep mine cooling.The results showed that the lower the temperature in driving head-on 5 to 7 ℃,the highest temperature is 30 ℃.Local cooling system can effectively alleviate the situation of heat hazard of local sites and improve the underground working environment.
- local cooling,
- mine heat injury,
- cooling effect
