Abstract


Original rock temperature is mine mine heat harm governance basic data analysis is carried out mine heat , airflow and temperature prediction underground mine cooling measures and the development of an important basis , but also divided mine heat damage level of the basic parameters. Mechanized mining face is a core part of mine production , which bears most of the tasks mine production of mine working face to study thermal environment of great significance . This paper systematically introduces the high-temperature heat damage of the basic theory of mine , briefly Zhenglong Coal Co., Ltd. of Henan coal thermal injury situation suburbs ; shallow hole fast temperature using the method of the original coal mines on the outskirts of rock temperature measured on the outskirts mine heat hazard classification of mine , come to suburban hot water is caused by the uneven distribution of coal original rock temperature of the main factors ; and thermal coal mine roadway parameters such as air flow and convective heat transfer coefficient were studied on the basis of 2501 on mine heat longwall face a quantitative analysis . Studied Merry Lane track in 2501 and 2501 fully mechanized mining face in the thermodynamic parameters of flow variation to identify the main reasons that cause airflow temperature . And on this track on the basis of 2501 and 2501 , Lane had mechanized mining face airflow and temperature forecasts. Based on these parameters , the mine can provide technical , reliable, economical and reasonable cooling technology solutions for the high-temperature thermal damage governance mine has great practical significance.
