2017-6-5 The total cost of mining includes the direct mining cost and social cost. The social costs include the impacts to the environment and socio-economic systems. According to the estimates for the complete costs of coal, coal mining only accounts for 22% of total social (external or “hidden”) costs of coal (Epstein, Buonocore et al., 2011).

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at

2021-2-17 Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include ...

2020-6-23 A semicontinuous process system consisting of a single-bucket excavator, truck, crushing station, and belt conveyor is the main coal mining process system of a large-scale hard coal open-pit mine. Through analyzing the coal mining production process, the key issues of coal mining truck flow optimization are obtained. Statistical method of using triangular fuzzy numbers analyzes the key time ...

2018-12-12 The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench production. Since the ...

1. The use of energy criteria to establish the mine boundaries corresponds to the role of coal-mining enterprises as subsystems within the energy-production system. The criteria here proposed reflect the level of technology not only within coal mining but also within the power industry and in transportation. It is important that the parameters included in the criteria have a physical basis ...
