Drawpoint Design in Caving and Stoping Mines
The design of drawpoints in caving and stoping mines has a significant impact on the productivity of the operation. Drawpoints must be designed to provide uniform drawdown and maximum recovery of the broken ore within the limits imposed by the dimensions of the stope, the stability of the pillars, the method of draw, material flow characteristics, etc. The design of drawpoints historically relied on the mining engineer's experience and intuition. However, in many operations, empirical analyses have also produced important information regarding design geometry. Factors that affect the sizing and spacing of drawpoints are discussed and guidelines are provided for their design in order to obtain maximum recovery of broken ore and reduce hang-ups.
