Openpit slope geotechnical considerations and its effects ...
Sep 25, 2019 · In openpit mining, a stable pit slopes design is essential for safe operation and economic performance of the mine. However, a steeper pit is more desirable from an economic standpoint due to reduced overburden removal. As the mine deepens, the openpit walls become increasingly prone to slope failure, which causes human and economic losses.
