An orebody model constitutes a threedimensional accumulation of mining units (blocks). The available metal content in a mining unit and the economic parameters, such as metal price, mining cost, processing cost, marketing or selling cost, as well as the metallurgical recovery, are used to calculate the economic value of a particular mining block. A mining block with a positive value is classifi...
In the production process of open-pit mines, trucks are applied in mines for transporting ores and rocks. Most equipped with dozens trucks. It is important to plan dispatch so that transportation can be shortest distance, lowest cost, most efficient. At present, many mining enterprises have realized use dispatching systems schedule complete tasks. However, these methods mostly designed deploy r...
In this paper, the blasting parameters are designed based on drilling data of exploration geological stage, geophysical and mechanical mining area, age information, numerical simulation layered rock steps is carried out to optimize parameters. Multiple sets tests were on-site, large block rate, average size satisfaction cost shovel loading efficiency, effect rate set as evaluation indicators, w...
