Abstract Synthetic aperture radar (SAR) technology has been widely used in landslide deformation monitoring the past decade. It advantages of high accuracy, a wide range, and flexibility allowing all-weather continuous monitoring. The self-developed S-SAR synthetic (slope radar) is first completely domestic-made slope equipment China, its performance technical parameters are equal to or better ...

In the case of Roşia Poieni open pit mine level +805 m was established as a daily operating limit; division into benches based on this by dividing horizontal slices with thickness 15 m, equal to height bench. Thus, there were 27 in Curmătura area and 23 Ruginiş area. The general slope angle set at 35°, for which tailings volumes implicitly opening-up coefficient calculated. stability analysis p...

We present an integer programming formulation for the open pit mine production scheduling problem. We strengthen this formulation by adding inequalities derived by combining the precedence and production constraints. The addition of these inequalities decreases the computational requirements to obtain the optimal integer solution, in many cases by a significant margin. & 2010 Elsevier Ltd. All ...

Here we report on a metagenomics investigation of the microbial diversity in a serpentine-hosted aquatic habitat created by chrysotile asbestos mining activity at the Vermont Asbestos Group (VAG) Mine in northern Vermont, USA. The now-abandoned VAG Mine on Belvidere Mountain in the towns of Eden and Lowell includes three open-pit quarries, a flooded pit, mill buildings, roads, and > 26 million ...

Optimisation tools which determine the best layout for access and haulage in an underground mine address an important and difficult mine design problem. The complexity of the problem can be compared to the task of optimising the final pit design in an open pit, together with the pit haul roads required. The strategic design of an underground mine layout must address the location of haulage shaf...

The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...

This study aims to fully explore the influence of rock joint roughness in slope stability analysis an open mine. Therefore, based on least squares parameter estimation method, a generalized shear strength coupling roughness, which is used evaluate design, was established by matching formula reflecting relationship between coefficient and parameter. Firstly, verify calibrate model, physical dire...
