<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 presents part of the work on ground vibrations induced by blasting, and to estimate safe maximum charge per delay to protect the nearby structures.

Underground stone mines in the United States make use of the room-and-pillar method of mining. A prerequisite for a safe working environment is that the pillars should adequately support the overburden and the pillar ribs and rooms should remain stable during ...

Moisture deterioration of clay-rich roof rocks causes high numbers of roof falls in coal mines in humid summer months. Rocks with high moisture content are generally weaker and can further deteriorate when subjected to wetting and drying cycles. As a result, ...

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 ...
