| According to the common installation position and the cold air conveying mode in the extracting coal face of high temperature mine, this paper analyzes the cold air changing process when it is translated to extracting coal face. It also analyzes the changing process of colder airflow status parameters. Then, the reason of change in cold airflow status with different installation position and cold air conveying mode is analyzed in detail. In order to achieve the optimal cooling solution in different installation positions of air cooler and air supply mode, the paper has taken the following steps: firt of all, it proposes the calculation method of air cooler exit parameter under different conditions. Calculation result must ensure the temperature of extracting coal face to meet the design requirement. Secondly, every part which constitutes the cooling capacity of air cooler is introduced under different cooling schemes. Thirdly, it qualitatively analyzes the size of cooling capacity needed. Results show that it is the optimum cooling solution when air cooler is far from extracting coal face and colder air is translated by saliva isolation. It can say that the above researches help to provide a guide for high temperature mine cooling system design. |
