<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 authors have been involved with the research on the short and long-term stability of ground above these abandoned mines. In this article, they present<br />the outcomes of their studies on the dynamic characteristics of ground and amplification of ground ...

<p>Risk analysis tools were implemented during closing activities on radioactive mill tailings disposal Bor&scaron;t, affected by a landslide. The probability of landsliding before and after remediation works was calculated and expressed through relaiability ...

This paper will review some methods used to manage geotechnical risk at Damang Pit Cutback. The pit depth is designed up to 250m with push back on the eastern and western walls of the existed and depleted Railway Cutback (RCB) pit. The geotechnical design ...

A risk study was carried out at the Cerrejon coal mine in order to assess the impacts of pit slope failure in terms of safety of personnel and destruction of equipment with economic consequences. Results of the assessment enabled the definition of risk treatment ...

Open pit slope design has conventionally been effected as a bottomup function utilizing available geotechnical information. This results in a decision criterion based on probability of failure and factor of Safety with a risk assessment being carried out on ...

Coal production from the 200 million tonne Curragh North coal resource in Central Queensland commenced in late 2005. The mine is located on the eastern floodplain of the Mackenzie River, and requires a 22 km long flood levee before operations can proceed. ...

Potgietersrust Platinums Ltd (PPRust) is Anglo Platinum’s only open pit operation. The major slope stability concern at PPRust is rapid, small-scale brittle failure on the west wall of Sandsloot open pit. In order to improve safety and mine more economically, ...

U.S. Mine Safety and Health Administration (MSHA) accident statistics have identified ore-pass hazards as a significant safety problem in U.S. underground metal mines. The statistics show that nearly 75% of injuries are directly or indirectly related to pulling ...
