Blasting Safety – Revisiting Site Security
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.
