Rational match of drill hole, bolt and resin diameters in a coal roadway
Abstract
Based on the result of the laboratory and field tests, a theory is put forward about the rational match among drill hole and bolt diameter, and the resin., whether the bolt has longitudinal reinforcement or not. The theory is important for selection of the design parameters for coal roadway support.
