The increasing expansion of open-pit mining and the drastic transformations land use in Latin America have led to processes rural depopulation among traditional inhabitants, causing unsustainability life systems. In context profound, worldwide territorial environmental transformations, it is necessary anticipate change scenarios identify territories prone depopulation. objective this article de...

Based on current researches and developments of open-pit mine slope in China, the engineering features of open-pit mine slopes are summarized. Mine slope is basically formed by dynamic excavation of multi-level and multi-type, and mining benefit is the purpose of mine slope engineering when using various schemes and/or methods. Thus, the issues of design and stability analyses are the main conc...

open-pit production scheduling (opps) problem focuses on determining a block sequencing and scheduling to maximize net present value (npv) of the venture under constraints. the scheduling model is critically sensitive to the economic value volatility of block, block weight, and operational capacity. in order to deal with the opps uncertainties, various approaches can be recommended. robust opti...

This article describes an approach of mathematical processing signals (seismograms) from five blasthole charges experimental blasting, each 3 m deep, with equal explosive weight (1 kg), and equidistant (3 m) one other. The seismic waves were measured at a 13 to 25 distance. provides spectral analysis, wavelet fractal analysis results. It defines the dependence dominant frequency amplitude on di...

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...

In this study, a three-dimensional finite difference numerical model of the Jinfeng Gold Mine, including surface topography, ore body, shafts, and main faults, was built to estimate shaft stability deformation induced by underground mining transferred from open-pit mining. Satellite monitoring data displacement at several points used calibrate model. The sequence excavation filling in simulatio...
