The open pit mine production scheduling (OPMPS) problem seeks to determine when, if ever, to extract each notional, three-dimensional block of ore and/or waste in a deposit and what to do with each, e.g., send it to a particular processing plant or to the waste dump. This scheduling model maximizes net present value subject to spatial precedence constraints, and resource capacities. Certain min...

Abstract Coal mining in China is continually increasing, and the associated emitted coal mine dust of growing environmental occupational concern. In this study, deposited (DD) was analysed three different regions an active, highly-volatile bituminous open-pit Xingjian Province, Northwest China: working fronts, tailings handling sites, road traffic sites. Samples were for particle size, geochemi...

Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with commitment to reduce CO2 emissions increase mine safety, companies have invested innovative, more sustainable technologies. The innovative truckless system, intensive use belt conveyors from processing plant, represents a...

Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...

The open-pit mine production scheduling problem has received a great deal of attention in recent years, both in the academic literature, and in the mining industry. Optimization approaches to strategic planning for mine exploitation have become the industry standard, as the recent review of Newman et al. [19] highlights. However most of these approaches focus on extraction sequencing, and don’t...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents role noise assessment control large-scale operations. Mine planning develops model operations, ore excavation, dumping scheduling processing rates, including spatial distribution activities. Such level min...
