Open Pit Mine Design, Planning & Engineering Mining

The challenge to SRK was to predict inflow to a large open pit mine from discrete, highly conductive faults then predict the behaviour of the post-mining pit lake. SRK undertook extensive hydrogeological studies at the Hycroft gold deposit that has culminated in predictive numerical groundwater flow models.

Environmental impact of mining Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
