PROTECT AND PRESERVE (SAFE EGRESS/AIR SUPPLY)

Escapeway and ventilation needs are always changing as we mine deeper at an accelerated rate. Sub-levels are further apart due to more accurate blasting, and mechanized methods of mining are creating massive excavations with reduced stope access points resulting in fewer ventilation options. There is an ever-growing demand for more efficient, more reliable and safer means of fulfilling egress and ventilation requirements. Descender is CIS’s innovative modular solution to rapidly constructing escapeways, and lining vent raises.
