Method and Mechanism of Dump Overlying the Bedrock with Large Dip Angle in Opencast Mine
Advances in Civil Engineering
Dump in the steep area of the open-pit mine is essential for safe production. The bedrock with the bumpy-surface blasting method effectively improves the stabilization of the dumpsite. The effect of the ratio and dispersion degree on the deformation and failure of the dumping bench at the largely inclined area was analyzed. Based on the limit equilibrium method, the equation about the stability factor and the blasted region ratio was deduced. Virtual experiments were performed to address howdoi:10.1155/2021/6632944 fatcat:6yxgupodjfawdn7jleaebqysru
