Panzhihua Iron And Steel Mining Company Zhu Mine South Slope Blasting Vibration Reduction Technology

In the southern outer leaf of Zhu Mine, the elevation of the top of slope is 1445 meters; the elevation of the lower part is 1270 meters; the relative height is 175 meters; the bottom elevation of surface mine is 1030 meters; ultimately the elevation of the slope near the outer leaf is 415 meters; but railway transportation line group which are used by the depth portion mining extend toward the depth portion along the southern outer leaf from 1270 meters levels of the close circle of surface mine.Applied research of Blasting reduction vibration Technology in the southern outer leaf of Zhu Mine of Panzhihuan Mining Company which is based on blasting design of Ma'anshan Mine Research institute, combing the hydrology and geology situation and the importance of the protection slope, through drilling and forming hole research, hole circuit parameter optimization research, analysis of blasting testing vibration and so on, so now and later inducements of Blasting vibration can be reduced as far as possible which probably cause landslide in the southern outer leaf, we can make sure that the slope i s steady and railway transportation line group which enter the depth portion run safety and economically and the mine regularly products.
