Coal mine bursts have represented a major hazard for U.S. mining operations for more than 90 years. During this time, many prevention controls have been developed and tested. This paper reviews 11 prevention control techniques. Although coal mine bursts are ...

Multiple seam interactions are a major ground control hazard in many U.S. underground coal mines. The two most common types are: Undermining, where stress concentrations caused by previous full extraction in an overlying seam is the primary concern, and Overmining, ...

Highwall mining is an important coal mining method. More than 60 highwall miners are presently in operation, and they may account for about 4% of total U.S. coal production. A review of accident data for 1983-2002 from the Mine Safety and Health Administration ...

Instrumented cable bolts developed at the Spokane Research Laboratory of the National Institute for Occupational Safety and Health were used in conjunction with existing ground control to monitor rock mass loads at various field sites (FMC Granger, Getchell, ...

This paper presents an overview of the most significant ground control hazards facing today's mineworkers. Analysis of recent fatality investigations and accident statistics identified certain job categories, mining techniques, and geologic environments that ...

<p>The Code introduces the requirement to install surface rock support in high headings(ie. those greater than or equal to a nominal 3.5m in height) in all Western Australianunderground mines unless a documented geotechnical risk assessment justifiesotherwise. ...

<p>What separates the support of mining openings from the support of similar civil engineering structures is the fact that mine openings have to survive large deformations as a result of changing stress conditions induced by progressive mining. Steel fibres ...
