RESEARCH OF THE EFFICIENCY OF USING «GEOVIA SURPAC» AND «MINESCHED» WHEN PLANNING MINING WORKS IN IRON QUARRY

Abstract

Purpose. Investigate and compare monthly mine planning method using Geovia Surpac and MineSched software. Methods. The computerized research method was used to create a scenario of mining operations in Geovia software for planning monthly operations in the open pit of LLC Eristovsky MPP. Results. It was confirmed that the new software make possible to plan the extraction of ore minerals for a certain period, with the possibility of uniform supply of the concentration plant with ore minerals of the required quality. Also, it became possible to analyze in detail the extraction of minerals from the contours of the open pit and clear production control in the working contours. Scientific novelty. The dependences of the given productivity of mining equipment on the parameters of the mining system elements were established using the MineSched software. The effectiveness of determining the quality of mining minerals is established, when planning for a longer period of time using computer programs in comparison with the old method. The economic benefits of using new software with broader functionality are determined. Practical significance. A new method of planning the ore mass extraction is proposed, which made it possible to supply minerals from the pit with average quality indicators. This contributed to a more efficient product enrichment, which in turn reduced production costs. Also by the new software it was possible to reduce the time for planning mining operations, which led to a decrease in working time to complete the task and, accordingly, reduced the cost of computing operations.
