Abstract

Aimed at the problem of useless hole sealing which caused low drainage consistence and low efficiency,in gas suction system of Jiulishan coal,on the base of original second hole sealing measures(inside sealing method),a three steps re-treatment measure(broken hole sealing method)was put forward which is "destroy hole、drill hole、subsection sealing ".Through the experiment of drainage hole in 14121 transport tunnel of Jiulishan coal,and compared with the inside sealing method measure,a result was proved that this method dealing with average drainage consistence is 2.52 times to the inside sealing method.
- drainage consistence,
- useless hole sealing,
- re-treatment measure,
- drainage hole
