Abstract:Rock bolting technology has already been used universally and created prominent technological and economic profit. This paper introduces the new research achievement of rock bolting technology for coal roadway. In rock bolting theory,it is considered that the main function of rock bolting is to control dilatancy and destroy in bolted surrounding rockmass,such as delamination,sliding and fracture opening,to maintain the completeness of surrounding rockmass to maximum extension,and to avoid harmful deformation. The technical parameters and operation methods of the geomechanics instruments are introduced,including small borehole hydrofracturing stress measurement device,wall rock strength measurement device and fiber borehole observation rig. The contents and characteristics of dynamic and informational rock bolting design method,computer design software for engineers and technicians in coal mines are discussed. The mechanical properties of high strength rock bolting materials,such as rock bolts,resin capsule,W-shaped strap and cable bolts are analysed. Finally,the rock bolting effect is evaluated through monitoring data in a case study. It is proved that the rock bolting is the most suitable supporting type for coal roadways in coal mines with high efficiency and low cost.
