Project Detail:
Opencast semi-mechanized method will be adopted using machineries such as Excavator, Wire saw cutter, compressor, jack-hammer, drill rod etc.
Mining operation is proposed to be in single shift (8 hours).
Firstly the weathered zone of 0.5-1.0 m will be scraped from the top. Then, drilling will be carried out by using jack hammers driven by air compressors.
Wire saw cutter will be used to detach the stone blocks from the quarry face.
Excavation & separation of decorative stone is done in two phases. One phase is removal of stone from the quarry face. The second phase is splitting-sizing-shaping.
Cutting and removal of main blocks from the face is done mainly by drilling machine, wire saw
cutter, jack hammer & with the help of excavator.
Splitting of this size stone is done by jack hammer & excavator for horizontal & vertical cutting.
Handling and loading of different sized blocks to stock yard will be done by hydraulic excavator.
Excavator and rear dump truck combination will be used for removal of rejected blocks from mine face to dump yard.
Transportation of marketable decorative stone blocks will be done by trailers/lorries/trucks to the respective destinations.
Total Project Cost: Cr. 11.4
