SIMULATION OF MINING INDUCED SEISMICITY IN DEEP …
To facilitate seismic simulation, a large set of circular flaws are generated in the rock mass surrounding the location of future mining excavation. The locations, orientations and radii of these planar discontinuities are randomly generated. It is assumed that a seismic event is triggered at a flaw when the resistance which binds the
Newmont's Tanami Expansion 2 momentum building
Newmont's Tanami Expansion 2 (TE2) in the Northern Territory – the largest mine expansion project in Australia – has seen some significant recent developments. The gold project, which is developing an extensive new materials handling system, including an underground crusher, conveyors and a 1.46 km-deep shaft hoisting system, is Newmont's biggest capital …
Seismic resilience enhancement for building structures: A …
In recent years, smart materials and structures have become a new developmental direction in seismic resilience enhancement technology. Researchers use electric/magnetorheological liquid material, shape memory material, piezoelectric material, electric/magnetostrictive material or other intelligent driving materials to develop electric, …

Performance-Based Seismic Design of a Screening Building for the Mining
3.1 Crushing Operation The selected building corresponds to the supporting structure of two screens within a copper and molybdenum production process. The plant has three identical screens buildings. ... Comments and future work The main intent of this study was to define a performance-based seismic design approach for mine facility buildings ...
Physically motivated moment-tensor decomposition for mining …
As proposed by Ryder (1988), seismic sources at mines can be broadly split into two main categories. The first of these is slip/shear in the rockmass, which can be described by a DC moment tensor. The second is 'crushing' failure in the rockmass near a mining void.

Crushing and Screening Handbook
'S MINING AND CONSTRUCTION TECHNOLOGY We have the expertise to build a fl eet of track mounted crushing and screening plants for pri-mary, secondary and tertiary stages according to your application. Moving along the quarry face the track-mounted units replace dump truck haulage, thus achieving substantial sav-ings.
Pounding impact on seismic demands for adjacent irregular …
When adjacent buildings undergo seismic shaking but are not adequately spaced apart, their individual responses differ in terms of mode shapes, durations, and magnitudes of …
HEARST MEMORIAL MINING BUILDING SEISMIC …
This paper describes the programming, planning, design, and analysis for the seismic improvements to a four-story brick masonry building originally constructed in 1907. The building is an historic landmark on the UC Berkeley campus, and is located very close to the Northern Segment of the Hayward fault.
Seismic Analysis and Design of Building Structures
This chapter is dedicated to introducing civil engineers to the seismic fragility analysis of nuclear power plants, introducing the fundamental concepts of seismic fragility analysis, and offering a case study to demonstrate its practical application. As a case study, seismic fragility analysis on a reinforced concrete shear wall was presented.
