The Research For Injury Impact Of The Mine Rock Slope With Weak Interlayer And Its Development Discipline And The Numerical Simulation

With the accelerated pace of development of market economy, China’s demand for energy has been increasing, making the open.air stripping technology has been widely used, but in open pit bench blasting vibration generated by operations on slope stability effects can not be ignored, and mine rock slope often have internal defects have weak interlayer, therefore, in the study of blasting vibration on the slope, the influence of blasting on weak tectonic region occupies an important position.slope stability evaluation of such and safety measures to prevent and to take significant.In this paper, combined with the measured data from blasting data in Xinzhou, Shanxi Coal Industry Co.Ltd. Mitac Ka moraine open pit mine, including acoustic measurement and vibration test, According to under the condition of different medium, acoustic velocity and vibration amplitude is different, its damage law also is not the same, by contrast, it is concluded that there is weak structure surface of slope under blasting vibration is the impact and damage degree than no weak structure surface slope, blasting vibration effect more vulnerable to damage, and by using Ansys software to simulate under four blasting vibration dynamic load for perturbation law of rock mass slope with weak interlayer, proved the correctness of the weak structural face the influence law of rock mass slope.
