| Abstract: | The general idea of pretension bolt with high strength (PBHS) is put forward by analyzing the weakness of the commonly-used bolt supporting. The function of PBHS to control the separation of stratified separation in coal roadway is analyzed. An effective control technology of pretension, which includes pretension bolts of high-quality, pretension trusses to be made of steel strand, and M-steel strands, is well developed. Finally an engineering instance of pretension supporting for road along next gob in Xieqiao coalmine is discussed. |
