On the parameters of an industrial motor vehicle designed to transport sized coal out of the face of an open pit

Abstract

Introduction. Sized coal production in the face of an open pit allows to reduce its prime cost by reducing transfers and backhauls. At that, the maintenance of the quantitative and qualitative characteristics of the produced coal is highly significant. For this purpose it is suggested that the coal’s transfer from the face to the daylight surface ought to be carried out in specialized containers installed on an industrial motor vehicle being the initial link in the resource-saving and ecological technology of sized coal transportation out of the face of an open pit. The research aims to determine and substantiate the parameters of an industrial motor vehicle for sized coal transportation in specialized containers out of the face to the daylight surface. Methodology. An industrial motor vehicle parameters determining mathematical model have been worked out, which allows to determine the rational values of its carrying capacity and structural parameters. Research methods include mathematical modeling and analysis, computer calculation software tools, and physical modeling. Results. The present work has determined the range of parameters and the alternatives of structural variants of an industrial motor vehicle adapted for the specialized containers with sized coal transportation out of the face of an open pit. Interdependences between its basic parameters among themselves and between its basic parameters and external factors have been examined. The dependences between the carrying capacity and the productivity of processing equipment, time of sized coal loading into the containers, and the dimensions of a freight platform. Conclusions. Dependences derived in the present work allow to determine rational values of industrial motor vehicle parameters and come into the substantiation of excavating and loading equipment and processing equipment for co-operation in the process chain of coal production in the face of an open pit.
