• Detection and Control of Spontaneous Heating in Coal Mine Pillars-A Case Study
  1/1/1995 - Reports of Investigations
  This U.S. Bureau of Mines study examined spontaneous heating episodes in coal mine pillars in an active underground coal mine. The objective of this study was to discover if the location of future events of pillar spontaneous heating could be inferred ...
• Technology News 434 - An 'Insulating' Shotcrete for Heat Abatement in Deep Mines
  5/1/1994 - Technology News
  The objective was to develop and demonstrate a lightweight material that has low thermal conductivity and that would be suitable for placement using shotcrete methods. This material could be applied in deep, hot mines where mine drifts must be insulate...
• Cause of Floor Self-Heatings in an Underground Coal Mine
  1/1/1992 - Reports of Investigations
  This report presents a Bureau of Mines study to identify the causes of self-heating events beneath the floor of a deep underground coal mine. The combined results led to the conclusion that pyrite oxidation was the prime cause of the heatings.
