Underground Mining Transportation Systems
Many underground mines use an inclined shaft fo r the transport of pe rsons, materials and equipment to and from the underground. Figure 3 shows an inclined drift at Ikeshima Colliery. Figure 3: Inclined shaft at Ikeshima Colliery The inclined shafts are often used also for belt conveyor transport, and therefore are
Underground Surveying | Point of Beginning
Another difference in underground surveys is that there often must be very short sights. In vertical shafts, it is often necessary to have two control points less than 20' apart since the points are transferred down the vertical shaft by wires or optical devices. And mine entries are often driven around 50' apart.
Underground Surveying Methods and Applications
Transferring the alignment underground For long tunnel excavation is carried inward from both parties. But vertical shafts are also sunk up to the required depth along the alignment of the tunnel at intermediate locations along the routes. The vertical alignment can be done by Plumb bob; Optical collimator; Laser
