Abstract

The peak pressure on the borehole wall is an important parameter for non-fluid solid coupling dynamic analysis of blasting. Aiming at the method for calculating the borehole peak pressure of the contour blasting, the interaction between explosion shock wave and elastic wall is theoretically analyzed, and the theoretical solution of pressure increase multiple after the collision of air shock wave and elastic wall is derived. The fluid solid coupling dynamic finite element numerical analysis method is used to study the blast air shock wave increase factor and borehole peak pressure under three kinds of rock mass media, two kinds of commonly used explosives for contour blasting, five common decoupling coefficients and two kinds of axial charging coefficient conditions. The results show that: the explosion shock wave increase factor of contour blasting is not a constant, and it is related to explosives characteristics, borehole medium conditions, decouple coefficient and other factors, correspondingly, the borehole peak pressure is also related to the above factors. Based on the statistical analysis results of borehole peak pressure simulation, combined with the theoretical deduction results and the commonly used calculation formula for the peak pressure on borehole wall, a new method for calculating borehole peak pressure in the contour blasting is proposed.
