<p>The purpose of this paper is to establish a qualitative method to estimate the risk level (e.g. rating and ranking) resulting from mining activity. Risk is the product of two factors: probability of failure and cost of consequences. A resultant assessment ...

<p>The field performance of a geotechnical structures including its failure mechanism should be evaluated in detail before construction in order to minimize the possibility of potential failure. In this paper, the application of soil nailing system is documented ...

<p>In this paper, ground movement in a highly populated region of Iran&rsquo;s capital city, Tehran, induced by excavation and construction of 7 the line of Tehran subway has been investigated. It was aimed to analyse the ground displacements and surface settlement ...

<p>The design of near-surface civil infrastructure requires detailed consideration of the geological/ geotechnical conditions, excavation geometry and sequence, and ground support measures to ensure stability of the underground openings and minimal impact ...

<p>For investigating floor heave behavior and controlling technique of roadway intersection in deep mine, creep deformation characteristics of floor around roadway intersection was studied by Flac3D and the effects of shear plastic critical value, reinforcement ...

This study consists of two case studies of landslides in natural slope: Lei Pue Street landslide, Hong Kong and Barabensi Landslide, Nepal. The first landslide transformed into a debris flow while the second one did not. Several numerical models (Slope/W, ...

<p>Pipe Roof Support systems are increasingly being used in weak ground tunneling although the design is often only based on experience. The results of an intensive measurement campaign, including settlement measurements ahead of the face, were used to determine ...

Molycorp, Inc.’s Questa Mine plans to switch from gravity draw in Block 1 to a load-haul-dump (LHD) draw system in the East and West blocks of the D Orebody. Changes in mining method require modifying the support design. This paper summarizes the numerical ...

<p>During the spring of 2003, the downstream slope of an embankment dam began to move during an extreme flooding event. The current study was implemented to evaluate the slope stability of the embankment and as a case-study to compare the limit equilibrium ...

Pseudostatic analysis is one of the simplest approaches used in earthquake engineering to analyze the seismic response of soil embankments and slopes. However, the choice of seismic coefficients used in the analysis can be arbitrary and generally lacks rationale. ...
