Evaluation of Coordination between Railway Transportation and Open-Pit Mining Based on Efficacy and Coupling
摘要
Abstract
In order to evaluate the coordination relationship between railway transportation system and open-pit production, a coupling degree model is established under the capacity-coupling theory. This model quantitatively analyzes the coordination level of mine production and transportation systems as well as the effects of subsystems and system parameters on the whole open-pit mining system. Besides, the indices of open-pit mining and haulage equipments, the parameters choice of wagon quantity, load and fluctuation in railway transportation are discussed, and an isometric transformation is applied using an improved efficacy method. Finally, a case study is conducted to verify the model ability in reflecting the real productivity. The results show that compared with expectation, a lower daily average number of wagons has a larger effect on the system coordination level, with only 20% contribution ratio of the minimum value of other indexes; however, the unbalanced factor of trains has a smaller effect on the system coordination. Moreover, the coupling index will be raised by 17% if the daily average number of wagons is increased to 80% of the original plan.关键词
