摘要
Abstract
Monomer column and bolting machine would use the downhole pressure water in roadway excavation,but with the extension of roadway,the working face of pressure water’s hydraulic becomes smaller because of local resistance and frictional resistance,which can’t meet the needs of normal pro-duction. Pneumatic supercharging device can make the working face water pressure to 8MPa,the monomer column quickly reach to setting load,which shorten the empty-support time and play the role of temporary supporting device,this is the basis for roadway rapid excavation of long distance working face.关键词
