Drawing on the theories of limit equilibrium and finite-element strength reduction, this paper explores instability modes stability change laws slope in zones E, W, S Jiajika spodumene mine, through rock mechanics tests, field survey, numerical simulation. The results show that sliding mode is circular arc or + plane sliding. Overall, final open-pit mine generally stable under current design, s...

Abstract Large-scale open-pit mining activities have profound impacts on the surrounding landscape and environment. At cessation of mining, rehabilitation large void spaces can be achieved by pit-lake filling, where water body provides a confining pressure mine surfaces, reducing both likelihood slope failure need for ongoing maintenance. Although pit-lakes present range long-term benefits, geo...

Due to uncertain nature of grade in ore deposits, considering uncertainty is inevitable in geological modelling of resources and mine planning. In other words, uncertainty in grade of mineralized materials, is one of the most significant parameters need attention in mine planning. In this paper, a comparative procedure utilizing Sequential Gaussian Simulation (SGS) and traditional Ordinary Krig...

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...
