| Abstract: | During tunneling along bottom in the three soft outburst coal roadway,the new high polymer grouting material malisan was applied to strengthen the roof of the roadway.The gas transfinite caused by top-coal caving was effectively prevented,thereby guaranteeing the construction safety and expediting the excavating velocity.This grouting method is easily enforceable,has quick response and obvious effects,so that it has the high expansive value. |
