Abstract
This article highlights the issues of transporting rock mass from deep horizons of a quarry using an automobile transport system. The paper describes an economic and mathematical model of the distribution of rock mass from the faces to the unloading points and substantiates the optimal transportation plan using a combination of methods of potential, Northwest corner and lowest costs, the purpose of which is to optimize the work during transportation of rock mass, along the quarry (lower and upper horizons). Using the economic and mathematical modeling method for the transport task, it is possible to minimize the cost of transporting rock mass to unloading points. Research in the field of modeling the process of transporting rock mass in deep quarries using various methods shows that optimizing the operation of the transport system under difficult mining conditions is possible only by building economic and mathematical models and comparative analysis of the results of these transport tasks.
Keywords
