Abstract: In view of the fact that presently, bolting support mechanism is not fully clear, a method combining mathematics with mechanics and theoretical analysis and numerical simulation with practical engineering measurement, and FRPA2D process analysis system software for rock breakage were used to make the dynamic simulation of the deformation and failure process of the wall rock in No. 9 coal-seam roadway in Wuhushan Coal Mine in Wuda coal area of Shenhua Group. The bolting support dynamic design method and rational design procedure were studied, reliability-based roadway bolting support dynamic design theory established and the related computer assistance system developed. Its industrial test in Wuhushan Coal Mine of Shenhua Group achieved good economic and social benefits.

Key words: Roof control, Process analysis system for rock breakage, Reliability design, Bolting support, Computer assistance system
