随着煤炭开采强度的增加,我国浅部煤炭资源日益枯竭,煤炭资源的深部开采已经成为了必然的趋势。但随着煤层埋藏深度的增加,地质条件也越来越复杂,高地压、多断层、大倾角煤层不断出现,给工作面的布置及生产带来了诸多限制因素及安全隐患。本文分析大倾角采煤工作面的热害机理,并分析了采煤工作面热风压的四种不同情况。 As the intensity of coal mining increases, the shallow coal resources in our country are depleted day by day. Deep mining of coal resources has become an inevitable trend. However, with the increase of burial depth of coal seam, the geological conditions are more and more complicated. High pressure, multiple faults and high angle coal seam appear continuously, which brings many limitations and hidden dangers to the layout and production of working face. In this paper, the mechanism of thermal damage in coal mining face with big dip angle is analyzed, and four different situations of hot air pressure in coal mining face are analyzed.
