数学模拟法是在数字电子计算机机能的有效范围内,工程技术人员可根据需要模拟任何真实情况。模拟时,对岩石裂缝的传播作了各种不同的假设,并把这些假设编入爆破区的模拟模型中。爆破机理假设炮孔为一个厚壁岩石圆筒,炸药起爆后瞬时高压气体充满炮孔,并产生压力即爆压。因为假定岩石是弹性体,所以在计算炮孔膨胀时,气体压力随炮孔的扩大而减小,直到平衡为止。这种瞬时加压产生了一个应变波,并在岩石中传播,使波
Mathematical simulation is the effective range of digital electronic computer functions, engineers and technicians can simulate any real situation as needed. In the simulation, various assumptions about the propagation of rock cracks were made and these assumptions were incorporated into the simulation model of the blasting area. Blasting mechanism assumes that the borehole is a thick-walled rock cylinder. After the explosive has been detonated, the instantaneous high-pressure gas is filled in the borehole and pressure is generated. Because the rocks are assumed to be elastomers, the gas pressure diminishes as the bore expands as the bore expansion is calculated, until equilibrium is reached. This instantaneous pressurization produces a wave of strain and propagates in the rock to bring the wave
