| The stability of open-pit slope affects the equipments and man in normal mine production. Producing blasting and siding-slope blasting largely affect the stability of slope. Blasting vibration will produce slope backlash loosening and cracking or caving. So is very important to research the influence of blasting vibration to slope stability and introduce feasible reducing-vibration measures. Confirming the space place of weakness plane, potential failure model of slope and comprehensive choosing of rock mechanical properties are discussed in the paper. The blasting vibration is tested and the consults are analyzed by regression analysis, binging forward the velocity and acceleration attenuating law of slope rock mass. The stability of two typical slope profile and sensitivity-analysis of the influence blasting vibration to slope stability are analyzed by Sarma method. Bring forward the technical measures of reducing the influence of blasting vibration to slope stability. |
