Cost of maintaining drifts at direct mining of a mine field
Authors:
Abstract
Establishing the cost of drift repair has always been and continues to be given much attention in mining engineering literature, as the maintenance of drifts is one of the main expenditure items of coal mines both in terms of cost and labor intensity. Some establish a mathematical dependence of the cost of drift repair for drifts driven (or closed) parallel to stoping operations as a function of their length, and others – as a function of maintenance conditions: the cross‑section of the working, rock characteristics, proximity to stoping operations, etc.
