• Technology News 517 - New Updates for NIOSH Coal Mine Ground Control Software
  4/1/2006 - Technology News
  Updates to the NIOSH suite of coal mine ground control software are described, including the Analysis of Roof Bolt Systems (ARBS), the Support Technology Optimization Program (STOP), and the Coal Mine Roof Rating (CMRR).
• Technology News 516 - ARMPS-HWM: New Software for Sizing Pillars for Highwall Mining
  3/1/2006 - Technology News
  The use of highwall mining systems has increased substantially in open-pit coal mines. It is used where overburden depth exceeds economical recovery. Highwall stability remains the major safety concern during highwall mining. The Mine Safety and Health ...
• Reducing the Risk of Ground Falls During Pillar Recovery
  12/1/2003 - Conference papers
  Pillar recovery has been associated with nearly one third of roof fall fatalities in underground coal mines during the past decade. This paper discusses design methods and technologies that have been transferred and implemented in mining.
• Deep Cover Pillar Extraction in the U.S. Coalfields
  8/1/2002 - Conference papers
  A study is described with the objective of evaluating the various methods and strategies by which panels, production pillars and barrier pillars are developed and extracted under deep cover, and to develop appropriate design guidelines.
• Technology News 492 - Proceedings of the Second International Workshop on Coal Pillar Mechanics and Design
  8/1/2001 - Technology News

• The Forgotten Denominator: Pillar Loading
  8/1/2000 - Conference papers
  This paper addresses a deficit in pillar loading research by exploring the accuracy of empirical abutment load calculations using insight provided by an elastic overburden model, a laminated overburden model and field observations.
• Analysis of Pillar Design Practices and Techniques for U.S. Limestone Mines
  12/1/1999 - Peer reviewed journal articles
  As underground stone mining expands to deeper cover and more efficient methods are used, effective stone pillar design methods become more important. In this paper, 72 stone mine pillar designs are examined for factors affecting stability.
• The State-of-the-Art in Coal Pillar Design
  3/1/1999 - Conference papers
  Recently, powerful design methods have emerged from analysis of large data bases of real-world pillar successes and failures. In the process, our understanding of pillar mechanics has been greatly enriched.
• Pillar Design Issues for Underground Stone Mines
  1/1/1999 - Conference papers
  This paper examines current design practices for stone mines and discusses issues for safe mine layouts so that a rational first approach towards balancing the demands for increased production can be weighed against increased risk to worker safety.
• Proceedings of the Second International Workshop on Coal Pillar Mechanics and Design
  6/1/1998 - Information Circulars
  A collection of 15 papers from leading international ground control specialists. The papers address the entire range of issues associated with coal pillars and have a decidedly practical flavor.
