Enhancing the adaptability of a mining complex in a dynamic environment by utilizing the technology for the development of a man-made deposit with a mobile ore preparation complex

Abstract

The paper deals with the issue of the development of man-made deposits of the bulk type, especially that formed during the development of iron ore deposits. An analysis of the actual state of man-made deposits was performed. Based on analysis the technology of man-made deposits mining was proposed. It involves the extraction of technogenic raw materials from the bulk and their separation according to quality characteristics using a mobile ore preparation complex. According to the proposed technology, the conditioned raw materials are sent to the processing place, and the empty rock is laid in layers in the created space. The parameters of the mining system were studied in the paper: the width of the excavator’s cut step is limited on the one hand by the unloading radius of the dragline, and on the other by the turning radius of the dump truck. A significant role is played by the raw material utilization ratio: the larger it is, the narrower the excavator cut step will be. The results of the research can be useful for design organizations and mining enterprises which implement resource-saving technologies.
