Stoping cost is one of the largest of the items comprising the total cost of producing ore. The cost per ton of ore mined is important but may be overemphasized if the more important cost, that per unit of metal recovered, is thereby overlooked. A given stoping method may give a low cost per ton of ore but, by reason of high dilution involving the handling, hauling, hoisting, and treating of a ...
To obtain a better understanding of why maintenance injuries occur, the U.S. Bureau of Mines has conducted a research project to analyze the design of underground mining equipment with respect to ease of maintenance and maintainer safety. The objective was to identify design factors contributing to these high injury rates and maintenance costs.

In an earlier Bureau of Mines publication it was pointed out that the cost of underground transportation constitutes a considerable percentage of the total mining cost in most mines, and in some mines may even exceed the cost of stoping. At 19 open-stope mines, transportation averaged 26.3 percent of the total underground cost; at 19 mines ...

productivity and lower unit operating costs than for comparable underground mines. However, the productivity and operating cost of an underground mine are heavily dependent on the mining method employed, the rock conditions, the quality and economic value of the mineral, and the degree of automation/mechanization amongst other factors.

Evaluate underground mining methods in the context of variable orebody conditions. Apply this knowledge to the underground mine design and mine planning processes. Perform selection and cost estimation of equipment for different underground mining methods.
Underground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining. Transport is also of critical importance in underground mines as is the mining operation itself. The underground transport system of ores, materials, equipment and persons has been developed from
The Equipment Cost Calculator is an online, interactive version of the Mine & Mill Equipment Estimator's Guide that allows you to change the parameters for calculating hourly costs, such as repair labor, diesel fuel, gasoline, natural gas, electricity and lubricants. This Calculator will allow equipment estimates in locales outside North America.
Preferred solutions are identified through detailed mine engineering and trade-off studies. 3D underground design, optimized production scheduling and mine cost modeling are used to assess project economics, beginning at an early stage in the planning process.
The primary objective of mine dewatering is to allow safe and efficient mining to be done Dewatering may impact the groundwater table which is shared with the local communities and environment. This article outlines the important parameters to consider when designing an efficient underground mine dewatering system.
Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …
A discussion of Underground Mining also loses much of its value unless costs are considered, because the expectation of profit is the only excuse for carrying on mining at all. As conditions vary they cause fluctuations in cost and there are few operations to which a definite cost can be assigned.
