The Impact of Mining Technology on Stability of Open Cast Mine

摘要

The article describes the aspects of mine workings when there are cracks in the rock massif of several systems. The research is intended to determine the massif stability around rocks. A methodology to determine strength parameters of rocks in the presence of cracks was proposed. The undertaken studies allowed developing reasonable data sheets for supporting mine workings in various mining and geological conditions. Processing of mathematical modeling results by using statistical methods allows significantly facilitating the calculation of maximum load acting on the support without resorting to direct modeling within the specified range of rock strength parameters. In this manner, it becomes possible to use this approach in a mining company without complex preparation of initial data to accompany the mathematic modeling.
