• Analysis of Practical Ground Control Issues in Highwall Mining
  8/1/2004 - Conference papers
  This article discusses highwall stability, reasons for early pull out of highwall miner holes, and geotechnical engineering and planning factors, as well as operating practices to improve highwall stability and minimize the risk of a trapped miner.
• Assessing and Monitoring Open Pit Mine Highwalls
  8/1/2001 - Conference papers
  This paper introduces warning signs of slope instability so operators are better able to recognize hazards. The most common slope monitoring equipment and practical methods of installation are discussed as well as the limitations of these systems.
• Analysis of Safety Aspects and Mining Practices for Effective Ground Control in Surface Mining
  8/1/2000 - Conference papers
  To determine causes of slope failure and highwall/spoilbank failure, this study reviews accident statistics, surface mining laws, the relevant literature, and observations from mine visits. The study emphasizes surface mines in WV, OH, and PA.
• A Radar-based Highwall Rib-Thickness Monitoring System
  1/1/1995 - Conference papers
  In addition to developing various types of cool-interface detection systems, the US Bureau of Mines is actively involved in developing a coal rib-thickness monitoring system for highwall mining applications. One particular system to detect the coal-air ...
