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 .

In underground mining situations, the mine roof conditions, ground support system, and ventilation are important factors in determining the extent of the blast area. In an underground gold mining operation in Nevada, blasting in a drift caused a roof fall in another drift situated about 25 ft below the blasted drift.

A critical safety component for all underground mining is intrinsic and standing support systems. Specifically, tabular hardrock mining exploits a wide variety of deposits that require various methodologies to safely mine the ore material. Several new support systems have been developed in recent years for hard rock applications which have
