ventilation arrangement in subleval caving mining layout

mining and mines Block Caving

Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grad Depending on how the ore is broken there are three block caving systems 1 The Grizzly system for fine material, 2 the slusher system for coarser material and 3 the LHD system for very coarse ,...

Concepts and types of ventilation

Ventilation moves outdoor air into a building or a room, and distributes the air within the building or room The general purpose of ventilation in buildings is to provide healthy air for breathing by both diluting the pollutants originating in the building and removing the pollutants from it Etheridge Sandberg, 1996 Awbi, 2003...

METHODS IN MINING BY SUBLEVEL CAVING

Applications of the sublevel caving hitherto used in mining have all had the same disadvantage in common with most other mining methods, viz the difficulties to provide an acceptable ventilation Usually the loading drifts have been put under negative pressure or suction and consequently via the caved materials sucked up fresh air coming from ventilation shafts or ,...
