Optimization of the trench level for the coal truck of an internal waste dump at the Anjialing surface mine
Abstract：The field situation at the Anjaling surface mine was used when computing the cost and work of truck transport.The transportation distance in the shovel-truck method was modeled as an equivalent length dual ring.A method based on differentiation was proposed to compute the transportation work around an irregular boundary.The trench level for the coal truck in an internal waste dump was optimized and the total cost of different schemes was estimated.The results show the lowest total expense at a 1 330 meter trench level.This level is located at the semi-stationary crushing station.A trench in the internal waste dump is the best way of reducing truck transport distances when the raw coal transport line is blocked.
