ESTABLISHING TOTAL AIRFLOW REQUIREMENTS FOR UNDERGR OUND

METAL MINES WITH TIER IV DIESEL EQUIPMENT ABSTRACT Traditionally, airflow requirements for diesel equipment operating in underground environments such as mines and tunnels were determined by multiplying the vehicle power by a ventilation rate that was either mandated by regulations(s) or determined empirically from known quantities.

Abstract - USGS

An additional cost of 7.5% is applied to all equipment purchase costs for freight. Equipment lists for the open pit models were based on actual operations, ad­justed to fit the generic nature of the handbook. Under­ground capital costs were determined by the amount of development necessary for an underground mine of the size and type under

The impact of mining conditions on mechanized mining

underground environment can run from 27000–30000 hours. A guaranteed hourly rate enables the customer to track cash flows on mechanized equipment (often a significant contributor to overall mining operational costs) over the equipment life. From an OEM perspective, guaranteeing the cost per hour and ultimately carrying all the risk of early life

Underground Mining Transportation Systems

Many mines also use trackless sy stems in drifts with gradients not steeper than 12 degrees. Large equipment, such as a continuous miner, is generally self-tramming in such circumstances. 3. Underground Transport for Materials and Equipment A variety of different systems are used for the transport of materials and equipment in underground mines.

Cost of Stoping for Underground Mining

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
