e) In underground mining haulage is a horizontal transport system. Bulk materials in mining are transported by haulage system. This can be described under two headings – track and trackless. Track haulage includes rope and locomotive haulage, which runs on rail or track. Trackless systems includes automobile (e.g. trucks), …
system are the ore/coal haulage and personnel transport systems, since the decisions are very difficult and not always possible in isolation from the other two. Important factors that affect the selection of the materials and equipment transport system are as follows: 1. Quantity (volume and weight) and size of materials and equipment. 2.

To ensure good support, the rope must contact the groove for approx 130-140° of arc, which leads to the following recommendation for the groove diameter: Sheaves With: • d = nominal rope diameter with 0/+4% tolerances; • d g = groove diameter. 1.05d < d g < 1.1d Optimal value = 1.075 dg During a wire rope's lifetime, the rope diameter ...
(D) A rope haulage is driven by an electric motor which develops 50 kW brake power when running at 1450 rpm. The rope is wound on a drum 1.3 m effective diameter driven by the motor through gear-ing having a speed reduction of 50 to I . Ifthe overall efficiency is 80%, calculate the hauling speed and the pull in the rope. l0 5. Group B
