The economics of extended pre-strip stripping - Research Online

Feb 15, 2013 . Extended pre-stripping allows truck-shovel operations to use double-side loading, which is known to be more productive. Taking an extended pre-strip pass increases the interburden bench width, which provides more room for drill and blast activities, including on-bench loading of explosives.

Underground mining (hard rock) - Wikipedia

Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas). Ventilation is also used to.
