Innovative numerical modelling of technogenic rock arrays structure

Abstract

Abstract. Numerical simulation of bulk technogenic rock arrays, unlike the full-scale, has a number of advantages. They are: the large amount of low cost measurements; operative selection of parameters necessary for the environment with the given properties; calculation of stress-strain state and assessment of the array sustainability; calculation of rock arrays filtration properties that are used as filters for mining enterprises sewage, etc. The article describes the method of numerical simulation of structure of bulk disjointed rock arrays, describes the basic initial and boundary conditions of the model; represents the numerical model visualization of the array, created with the use of peripheral dumping (as an array with more textured and visual segregation of granulometric composition adjustment). The basic applications of numerical modeling of technogenic rock arrays in the mining processes are described. Comparative analysis of the real and simulated array structure shows the adequacy of the numerical model and the developed for its creation algorithm, which in turn allows judging the quality of the study. Also, the adequacy of building models is supported by a high convergence of the experimental and calculated figures depending on the filtration rate values of the particle size distribution of technogenic rock arrays.

The Study of the Main Indicators of the Local Environmental and Economic System “Industrial Enterprise-Environment”

“…The analysis requires a practical application related to organizational, economic, infrastructural and technological solutions aimed at reducing the negative load, especially of production and consumer waste [2,14,15].…”

Efficiency of Low-Profile External Dumping at Open Pit Coal Mining in Kemerovo Region

“…Also, this dumping pattern allows optimizing the process of overburden transportation from the quarry to the dump taking into account the variation in the transportation distance that is, reducing or increasing the transportation distance from the largest to the smaller, depending on the overall technical and economic situation of the mining enterprise. Another reason to consider the low-profile external dumping is increasing dump's stability as an important ecological factor [14][15].…”

Modeling of Three Flat Coal Seams Strata Developing at Open Pit Miming

“…In addition, because of the flat bedding of the coal seams of open pits of South Kuzbass (Western Siberia, Russia), the height of the rock mass, which is processed by transport technology, is constantly increasing [9][10]. At present, this has led to a decrease in the speed of moving the front of mining work of the transport zone and, as a result, to the inhibition of the development of the transportless [11].…”
