Study on Gas Distribution Rule of 8104 Comprehensive Mechanized Caving Face in TASHAN Mine
NIU Jianhua
Abstract： 8104 Comprehensive Mechanized Caving Face is confronted with gas disaster in TASHAN Mine , it is propitious to up-grade validity of gas prevention for predominating its gas distribution rule exactly.In the text, In the text, gas consistency was de-termined by making use of drill bore method and beam tube monitoring method respectively in goaf , and the stope was caved up some cells in the work face, and the gas consistency was determined too.The research result are as follows:in the goaf of 8104 Comprehensive Mechanized Caving Face in TASHAN Mine , the gas consistency assumes the increscent trend from bottom to top;the trend is also increscent from outside to inner , and its trend may be set off three phases;the area from NO.100 bracket to the top corner in working face is the mass area of gas effusing from goaf , and it is main area when gas was fathered.
