Modern development of coal mining industry in Kuzbass is carried out using advanced techniques. Analysis its geological and technological conditions performed with respect to the technologies related methods, developing combined (open-pit underground) geotechnologies for complex deposits.

n A common decision in openpit mining is to determine the extraction sequence of notional three-dimensional production blocks so as to maximize the net present value of the extracted orebody, while adhering to precedence and operational resource constraints. This openpit block sequencing (OPBS) problem is commonly formulated as an integer program, with binary variables representing if and when ...

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...

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due numerous benefits than conventional truck-and-shovel systems. However, implementation of IPCC system can reduce flexibility introduce additional sequence requirements. This paper investigates long-term production scheduling crusher relocation plan open-pit mines using a semi-mobile high-angle con...

The Iberian Pyrite Belt (IPB) hosts one of the world's largest accumulations of acidic mine wastes and pit lakes. The mineralogical and textural characteristics of the IPB ores have favored the oxidation and dissolution of metallic sulfides, mainly pyrite, and the subsequent formation of acidic mining drainages. This work reports the physical properties, hydrogeochemical characteristics, and mi...

Tropical forests are among the most diverse ecosystems in world, completed by huge biodiversity. An expansion natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices needed as an effort reclaim their function. This paper summarizes existing practice of coal mining, covering regulatory aspects reclama...

This paper raises important questions about the way we approach numerical analysis in rock engineering design. The application of advanced models is essential to adequately analyze and design different geotechnical aspects pit-to-cave transitions. We present a critical review methods centered around hypothesis that model not, cannot be, perfect imitation reality; therefore, modelling large-scal...

The uncontrolled spread of illegal artisanal small-scale gold mining (ASM), popularly termed “galamsey” in Ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. A lack of understanding, however, of the types of galamsey, their operational attributes, and their relative impacts has unfortunately hindered an effective policy response despite num...

determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. one of the important operational con...

The paper substantiates and proposes a method for selecting mechanization tools crushing conveyor complexes as part of cyclic-flow technology in open-pit mining. proposed methodology justifies the types means complex used at Yoshlik-1 quarry JSC “Almalyk mining metallurgical combine”. task developing optimal technological parameters equipment conditions is formulated. Optimal were selected usin...
