• Issues for Training an Evolving Emergency Management Workforce: A View from the U.S. Mining Community
  5/1/2002 - Conference papers
  This paper reviews research from the U.S. mining community to define issues relevant to an evolving national and international workforce and relate them to the emergency response population.
• Motion Editing and Reuse Techniques and Their Role in Studying Events Between a Machine and its Operator
  4/1/2002 - Conference papers
  The first part of this paper is a review of several new techniques developed to facilitate the manipulation, noise reduction, storage and reuse of captured data, which have a potential to reduce the overall cost of motion simulation and improve its real...
• FLAC Simulation of Split-Pipe Tests on an Instrumented Cable Bolt
  4/1/2002 - Conference papers
  Researchers have conducted a large number of experiments on cable bolts to determine their load characteristics for different grout types, grout ratios, and cable configurations (Garford bulb, buttons, birdcage, nut cage, etc.)
• Use of Ground Penetrating Radar and Schmidt Hammer Tests to Determine the Structural Integrity of a Mine Seal
  2/1/2002 - Conference papers
  Over the years, more than 20,000 mine seals have been erected in underground coal mines in the United States. The National Institute for Occupational Safety and Health is conducting research to develop design guidelines, to investigate noninvasive tech...
• Improving Silica Dust Control Through Targeted Research
  2/1/2002 - Conference papers
  NIOSH conducted a strategic planning effort to identify those areas in mining with the greatest research needs. In response, the Pittsburgh Research Laboratory (PRL) has implemented a multi-faceted research program to improve silica dust control for the...
• A Summary of Fatal Accidents Due to Flyrock and Lack of Blast Area Security in Surface Mining, 1989 to 1999
  2/1/2002 - Conference papers
  This paper summarizes flyrock and blast area security fatalities from 1989-1999, examining causative factors. Accident data indicates that flyrock and lack of blast area security were primary causes of blasting related injuries in surface mining.
• Seismic Event Data Acquisition and Processing: Distribution and Coordination Across PC-Based Networks
  2/1/2002 - Conference papers
  NIOSH has developed an automated PC-based seismic event (induced earthquake) monitoring system for use in mine ground control studies. This paper describes system design philosophy, hardware/software components, installation examples, and results.
• 60 Years of Rockbursting in the Coeur D'Alene District of Northern Idaho, USA: Lessons Learned and Remaining Issues
  2/1/2002 - Conference papers
  Sixty years of rockbursting in the Coeur d'Alene district has taught painful lessons and led to practical advances in controlling rockburst hazards. This paper summarizes those lessons, concentrating on practical measures to reduce hazards.
• Investigation of the Jacking Force Capability of Tunnel Liners
  2/1/2002 - Conference papers
  Steel liner plates are used to provide protective linings in the tunneling industry. This report summarizes test results, examines design parameters that impact jacking force capability, and develops models to improve design load prediction.
• Silica Dust Sources in Underground Metal/Nonmetal Mines - Two Case Studies
  2/1/2002 - Conference papers
  The ultimate goal of this research is to develop control technologies to reduce worker exposure to respirable silica dust. Dust surveys were conducted in an underground limestone and gold mine to investigate silica dust sources, generation levels, and ...
