Descender – Escapeway

Solid Steel Escapeway and Vent Raise Solution

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, mechanized methods are creating larger excavations and reduced stope access points are resulting in fewer ventilation options. Creating an ever-growing demand for more efficient, more reliable and safer means of fulfilling egress and ventilation requirements. Descender is CIS’s innovative solution to rapidly constructing escapeways, and lining raises, shafts and ore passes.
