Heidaigou open- pit coal mine design and implementation of presplit blasting optimization scheme
Abstract：hrough Heidaigou open - pit coal mine provide theoretical support pre - splitting blast blast hole layout parameters, charge structure, detonating network design and optimization, reasonably determine the appropriate pore network parameters, front resistance line and millisecond time. And factors, thus realizing the ensure blasting quality premise effectively reduce the vi- bration of the slope presplit blasting, improve the quality of purpose.
