One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader eet. This problem is the Equipment Selection Problem (ESP). In this paper, we describe the ESP in the context of surface mining. We discuss related problems and applications. Within the scope of

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation.

CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act of 1976 charged OTA to assess the feasibility of the use of deep-mining technology on leased areas. With the passage of the Sur-face Mining Control and Reclamation Act of 1977 congressional interest in the study of deep underground mining technology shifted

Equipment Availability. Definition: "Equipment Utilization" measures the percentage of time a piece of equipment is actually operationally in a 24 hour day, for a given period of time.The performance measurement is the productive time expressed as a percentage of the total time available. Responsibility: The reporting of Equipment Utilization is the responsibility of the Production Controller.

Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment.

Equipment life-cycle cost analysis (LCCA) is typically used as one component of the equipment fleet management process and allows the fleet manager to make equipment repair, replacement, and retention decisions on the basis of a given piece of equipment's economic life. The objective of this research is to develop a robust method that
