Abstract

© 2018 University of Minho. All rights reserved. Diesel is used for operating Heavy Earth Moving Machines (HEMM’s) such as excavators, dozers and dump trucks in an opencast mine. The energy share of HEMM’s is about 64% of total energy usage in conventional opencast mine. The specific diesel consumption (SDC) is a performance indicator used to assess and compare the energy performance of HEMM’s in mines and is defined as the ratio of total diesel consumed to the composite production. The SDC of the coal mines in India varies with the mining method, equipment characteristics, mine gradients and material handling rate. SDC also increases with increase in mine area and depth. In this paper, a framework is proposed for benchmarking SDC of the coal mine using statistical approach. Five opencast coal mines of India with different mine and equipment characteristics have been compared to calculate the minimum SDC. The statistical approach has been applied for estimating benchmark SDC of a sample of mines by comparing the SDC using cross sectional data of different mines.The benchmark SDC of the mine is estimated to be 0.66 l/cu.m.The results are verified with SDC of best practices mines. A linear regression method has been used to develop a mine specific model for estimating SDC.A case study of an Indian opencast mine resulted in minimum SDC of 0.81 l/cu.m for a specific mine and that obtained between mines is 0.66 l/cu.m (25 MJ/Cu.M). The diesel saving potential by comparing minimum SDC with average SDC of a specific mine is 12.9 % and between the different mines is 33%.
