Numerical Simulation of Roadway Deformation of Different Cutting Aperture
Using ANSYS finite element analysis software, the crushing effect and wall rock deformation of a small high-pressure jet impacting coal were given numerical simulation analysis. It verified that impacting increased exposed area of coal in punch, providing conditions for pressure relief of internal coal seam and gas seepage. through comprehensive analysis of the rock stress and coal displacement of different roadway models after undercutting, it was determined that aperture size was 4/15 or so of roadway floor length, thus roadway fissures developed full, and maintained rock integrity, in favor of speeding up the face driving.
