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.
Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining.
Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
