Accounting for creep of the rock mass around the sides of the quarry

Abstract

Since open-pit mining operations on the elements of development systems have areas with dynamically changing stresses and deformations of the rock mass, the stress-strain state of the array around the sides of the quarry is considered. The objective of the research is to determine the parameters of the stress-strain state of the array that affect the stability of the sides of the quarry. Studies are conducted to determine the parameters of the stress-strain rock mass around the sides of the quarry. A mathematical model has been developed for determining the factors affecting the stability of the sides of the quarry. A multifactorial mathematical model of the stability of the sides of the quarry from mining geological and mining technical factors was obtained, taking into account the creep of the rock mass of the sides of the quarry. According to the formula obtained for the multidimensional model, it is possible to find a set of factors affecting the stability of the sides of the quarry. The obtained dependence makes it possible to determine the desired value from the known values of the factors.
