Abstract


With the the Mine increased mining depth and mining mechanization continuous improvement , deep heat injury has become one of the major problems of coal mine safety mining constraints . High temperature thermal environment of the mine not only reduce labor productivity affect economies of mine , and seriously endanger the health and labor safety of the miners . Therefore, how to improve the climatic conditions in the mine , to prevent heat damage , ensure safety in production , speed up China mine cooling theory is an urgent task required by the mine production reality . The subject of this study is based on the status quo of China 's deep mine temperature problem , summed up the domestic and international status and level of the air temperature and humidity prediction theory , analysis of the existing problems . The basis of research on the experiences and lessons of the national coal mine to solve the high temperature on the absorption of existing research results , using the method of combining theoretical studies and computer simulations to study for mine ventilation capacity , temperature and humidity prediction and design to provide a scientific basis . Based on the principle of the mine air and moisture exchange , the the roadway wall surface and wet coefficient of concepts and the end of the roadway moisture content and relative humidity calculation method , the use of existing theoretical formula deduced roadway temperature, humidity , airflow . Preparation of a high degree of visualization , fast speed , friendly interface , easy to operate the actual computer software and computer visualization techniques . Analog predictive analysis the mine ventilation status of the mine ventilation and cooling system transformation program to determine the ventilation, cooling system optimization program ; , mine ventilation to achieve mine ventilation and cooling management more scientific , safe, reliable and safe and economic operation of the cooling system .
