Selection and assessment of the stripping system in open pit mining of steeply dipping deposits

Article preview

Selection of the type and parameters of the stripping scheme is one of the most complicated tasks in design of the mining of steeply dipping deposits. The stripping scheme adopted in the project largely determines the capital and operating costs of mining and affects the development strategy of the company in general. The greatest number of alternative stripping methods are associated with mining conditions of reserves in large steeply dipping deposits, which were exploited for several decades. Current approaches to selecting the method and scheme of stripping involve the use of a specific type of transport; however, the type and model of the vehicle are not taken into account in the current classifications of stripping methods and schemes. It is necessary to develop a systems approach to selection of the stripping methods for mining steeply dipping deposits. The purpose of the study is to substantiate the parameters and develop a multifactorial criterion for assessing the stripping system for selecting an alternative for the development of a mining plant. The article proposes an approach in which the choice of the opencast transport, substantiation of the stripping method and scheme will be considered as part of the stripping system, which will allow a comprehensive solution of the problems of increasing the efficiency of mining at different stages of quarry operations. A refined definition and structure of the stripping system are proposed. As a criterion for assessing the efficiency of the stripping system, a rank coefficient is selected that takes into account the target values, the weight of parameters and groups included in the calculation, the computation of which is based on the use of a combination of multicriteria analysis methods. The approach allows considering not only the economic performance, but also other factors, which largely determines further development of the plant. The study primarily focuses on deep open pit conditions of ore deposit mining. The established rank allows choosing the most efficient strategy for the development of mining plants.
