Abstract

The mining companies are facing increasing pressure to their reduce production cost and their environmental impact from mining. This is occurring while the ore bodies are going down in grade and being found in more remote locations. Prices for products mined are today at reduced levels as the global economy balances supply and demand. All the factors bring forth the need for mining companies to make proper decisions when selecting their equipment in order to maintain low costs. Drilling equipment can be powered by either diesel engines or from the mine site’s electric power grid. Each of these options has associated costs and benefits. This paper examines the factors related to the cost of operating large diameter drilling equipment powered with electric motors to those powered with diesel engines for surface mining. Recommendations based on research, data analysis, and personal interviews direct and indirect from mine operators. This is intended to be useful reference for mine planners, operators and mine management to aide them in making an informed decision. The key factors are identified and discussed as a foundation to build a formal analysis for the specific application and sites where this power decision needs to be addressed. Recommendations related to Sandvik’s large diameter rotary drill offering are also presented.
