Question 1
What type of loading arrangements may be found on a roadheader?
Question 2
Students are to design a suitable ore pass to transport ore a vertical distance of 200m from the extraction level to the transport level of a block caving mining operation. The proposed maximum lump size for the operation has an equivalent circular diameter of 500mm. The ore material will contain fines and there is a possibility of clayey materials. The ore pass will be developed in a high strength metamorphosed rock mass. Key elements should include:
1. Ore pass diameter
2. Lining materials
3. Dealing with oversize material
4. Delivery arrangements at the base of the ore pass (the ore is delivered onto a 54 inch cable belt conveyor)
