Why is it crucial to manage the water table around an open-pit mine?

Managing the water table around an open-pit mine is crucial for several reasons, primarily to ensure slope stability, improve working conditions, reduce operating costs, and prevent environmental contamination. A high water table can significantly reduce the stability of open-pit slopes. Water pressure within the rock mass reduces the effective stress, which is the force holding the rock particles together, thereby decreasing shear strength and increasing the risk of slope failure. Managing the water table by dewatering the area aro....
