The operating environment of the mine is dynamic with many unknowns that can affect the equipment utilization drastically.
EQUIPMENT SELECTION b Face Supports. While it is frequently argued correctly that all items on a longwall face have to be considered as parts of an integrated unit and be fully compatible, it cannot be denied that poorly designed and inadequate roof supports are likely to have a greater effect on results than other items, and to that extent are more important.
mining costs and subsequently higher profits. Haul roads and ramps are the lifeline of the open cut mine. Road design must accommodate a number of factors and expected weather conditions, the largest vehicle on site and the speed of operations are taken into account in the design process.
When it comes to hauling ore, conventional wisdom would indicate that buying a bigger truck will result in greater productivity. While it s true that more is being hauled with every truckload, there are a number of considerations that may lead to the conclusion that that bigger isn t necessarily better. The benefits that larger trucks bring to the operation may be offset by ...
