MINE OPTIMISATION PROGRAM TO EVALUATE ECONOMICS OF DSI SNAKE HIGH ANGLE CONVEYOR IN OPENCAST MINE
ECONOMICS OF DSI SANDWICH HIGH ANGLE CONVEYOR AND ITS COMPARISON WITH IPCC & DUMPER TRANSPORT IN OPENCAST By Shyamal Kumar Bag DSI Sandwich High Angle Conveyor (HAC) is a special type of conveyor system, where the material is hugged between the top and bottom conveyor belts and carried at any steep angle up to 90 degrees. The system is able to elevate material high in a limited horizontal space. This system can be imagined as an elevator in a high-rise, where one can easily reach the top floor in minimum time and without effort avoiding the staircase. Since DSI Snake HAC angle covers the material from both top and bottom, hence, there is no chance of dust generation during operation. In deep opencast mine, the DSI HAC can be an ideal & most economic system for transport of material from pit-bottom to surface through the sidewall of mine (35 to 50 degree)as an alternative to dumper transport or in-pit conveyor system runs through haul road, where the gradient is limited to
