slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...

In this study, the Lagrange element strength reduction method is used to explore slope stability and as an evaluation of underground mining end-slope coal in a rock-stability analysis. A numerical analysis model established herein using geological conditions for coordinated open pit with area Anjialing Open-Pit Mine Underground No. 2 Mine. Additionally, evolution law open-pit studied proposed s...

A crucial problem in the mining industry is to determine the optimal sequence of extraction of blocks, in which the mine has been structured for exploitation. Typically a mine can be constituted by several thousands or millions of blocks. The sequencing models for this structure are very complex giving rise to very large combinatorial linear models. Operational mine plans are usually produced o...

In order to reduce the large rocks produced by blasting of hillside open-pit mine with heterogeneous and complex rock mass in arid area, based on lithology characteristics Dabancheng Limestone Hillside Open-pit Mine Hongshun, Xinjiang, key technology for homogeneous is proposed this paper. We can conclude from experiment that (1) it preferable have a detonation network realizes multi-stage mill...

This paper reports about an experience concerning the implementation of a WEBGIS, a BLOG and an ontology. WEBGIS and BLOG allow to promote a spread of spatial data knowledge, to consult planning documents in the Internet, increasing transparency level of programming choices and involving different stakeholders participation. The ontology is intended as an in progress powerful tool, increasing k...

The purpose of this article is to examine the applicability of Universal Thermal Climate Index (UTCI) index as an innovative index for evaluating of occupational heat stress in outdoor environments. 175 workers of 12 open-pit mines in Tehran, Iran were selected for this research study. First, the environmental variables such as air temperature, wet-bulb temperature, globe temperature, relative ...

In this paper, an infrastructure for monitoring remote equipment and solving some of the logistic challenges of operating satellite surface mines is presented. This infrastructure includes strategies for communicating timely and accurate information amongst operators, planners and supervisors, using off-the-shelf network protocols. Advanced data visualization techniques are implemented, so user...

The main objective of this study was to synthesize scientific knowledge in order to characterize Whole Body Vibration (WBV) in open pit mining: sources, measurements methodologies and main effects on health. A review based on PRISMA Statement was done. Inclusion criteria were research on WBV in mining, published after 1990 and written in English. Thirty-three studies were included in the review...

This paper proposes a newmathematical framework for the open pit mine planning problem, based on continuous functional analysis. The main challenge for engineers is to determine a sequence of nested profiles maximizing the net present value of the mining operation. The traditional models for this problem have been constructed by using binary decision variables, giving rise to large-scale combin...

In order to carry out an open pit mining operation, planners must periodically prepare what is known as strategic mine plan. This is a tentative production schedule for the remaining life of the mine that defines which area of a mining reserve will be extracted, in what years this extraction will take place, which resources will be used for the extraction, and how the extracted material will be...
