<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 ...

A partial shaft pillar extraction project was embarked on at a mine in the West Wits mining region in South Africa. Prior to the extraction, a rock engineering assessment was conducted with the main objective being to establish which areas of the shaft pillar ...

Classifying the rock mass is widely seen as being the fieldwork required to characterize the rock mass and enable the application of empirical design methods associated with the different classification systems. This paper argues that it is fundamentally important ...

A comprehensive study on the chemical composition of rainwater was carried out in Obuasi, a gold mining town in Ghana. The result of this study generally suggests that rainwater chemistry in the area is strongly influenced by local anthropogenic sources (mining). ...

<p>Presently, due to ever-increasing demand of minerals for the country, it is very much required to have the opencast mines at a greater depth. Increasing depth also increased the severity of slope stability problems of the opencast mines. Unlike the previous ...

Many states allow construction of landfills over previously mined areas. However, mitigation of the underground mines by filling or removal is often required prior to landfill construction. A settlement analysis for the proposed vertical expansion of a residual ...

This paper discusses the environmental impacts of dimension stone mining and recommends effective means for dealing with the practical aspects of reclamation and mine closure in dimension stone mining within the context of environmentally responsible business ...

Platinum mines produce large amounts of inorganic tailings containing high levels of metals which are disposed of on tailings disposal facilities (TDFs) and there is no information available on their possible effects on the surrounding terrestrial environment. ...

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 ...

The ISGS has prepared this publication in order to provide information to Illinois homeowners concerned with or experiencing subsidence problems associated with past mining activity. Common damages and problems associated with subsidence are described. Some ...
