• Pillar and Roof Span Design Guidelines for Underground Stone Mines
  5/1/2011 - Information Circulars, Safety guidelines, tips, and checklists
  This document presents the results of research conducted by NIOSH in cooperation with participating underground stone mines to develop generally applicable guidelines for designing stable pillars and roof spans in stone mines.
• Pillar Strength in Underground Stone Mines in the United States
  1/1/2011 - Peer reviewed journal articles
  Stone mines in the eastern and midwestern United States use the room-and-pillar method of mining to extract relatively flat-laying sedimentary formations. A survey of pillar performance was carried out to identify potential modes of instability.
• Roof Span Design for Underground Stone Mines
  7/1/2010 - Conference papers
  In this paper, the findings of a survey of roof span stability issues and design practices are presented, and the observed factors contributing to roof instability are discussed.
• Roof Monitoring Helps Prevent Injuries in Stone Mines
  11/1/2000 - Peer reviewed journal articles
  The Roof Monitoring Safety System (RMSS) is described, compared to other roof-monitoring technology, and described in context with proactive ground control plans for stone mines.
• Roof Monitoring in Limestone - Experience with the Roof Monitoring Safety System (RMSS)
  1/1/2000 - Conference papers
  This paper outlines the evolution of the RMSS and how it can be used in a comprehensive, proactive ground control safety program. A case history describes the RMSS being used to evaluate a mechanical impact sealing machine at a limestone mine.
• Controlling Roof Beam Failures From High Horizontal Stresses in Underground Stone Mines
  8/1/1998 - Conference papers
  A design technique is presented which provides stone miners with a method for making stability assessments. The consequences of widening rooms, changing geology and horizontal stresses, and different rock bolts on roof beam failure are discussed.
• Technology News 475 - Roof Monitoring Safety System for Underground Stone Mines
  8/1/1998 - Technology News
  The Roof Monitoring Safety System (RMSS) provides a safer, simple, and inexpensive means for measuring roof movement; its use in underground stone mines is described.
• Methods to Reduce Potential for Massive Ground Collapses in Underground Stone Mines
  3/30/2023 - Research projects
  A project investigating massive ground collapses and ways to reduce the potential for collapse events.
• Ground Control Research for Improving Safety Performance in Underground Stone and Other Large Opening Mines: Design, Monitoring and Risk Management
  2/23/2023 - Contracts and cooperative agreements
  A capacity-building contract with Virginia Tech University on ground control research to improve safety performance in underground stone and other large-opening mines.
