The procedure of planning the face shovels layout using the technologies of the Mining and Geological Information Systems

Abstract

Introduction. The article considers options for face shovels layout in an open pit based on the developed procedure of mining operations scheduling, which uses block modeling and considers the throughput of rock mass at the horizons, the length of the active extraction front, the quality of the mineral, the specified intensity of excavation, the accepted models of shovels and other attribute electronic data. The approach proposed in this procedure allows to consider many options for face shovels layout in an open pit and choose the best option in a short time in a semi-automatic mode. Research objective is to develop a method for automated layout of shovels along the working horizons of an open pit, based on the results of block modeling. Methods of research. Face shovels layout on the working horizons of an open pit is based on the calculations, computer modeling and technical and operating parameters of shovels, as well as the active extraction front assessment. The main step in solving the problem is to build ore body block models, simulate mining operations, and built an open pit model based on the periods of field development. Based on the results of block modeling, the optimal length of the excavating block on the working horizon for the selected face shovel model is determined. Research results. Based on the block model, shovels layout along the working horizons of the open pit is designed. Conclusions. The proposed procedure, in a short time in a semi-automatic mode, allows to solve the problem of lower horizons opening in deep pits, consider numerous options for face shovels layout in an open pit and choose the best option, minimizes production risks when developing complex deposits and carrying out comprehensive extraction of raw materials.
