• Analysis of Acoustic Responses of Domal Salt Mine Samples
  1/1/1990 - Reports of Investigations
  The Bureau of Mines has developed an acoustic test for determining if a rock salt sample is from a "normal" nongassy salt face or from a gassy face where an outburst has the potential to occur.
• Investigation of Methane Occurrence and Outbursts in the Cote Blanche Domal Salt Mine, Louisiana
  1/1/1988 - Reports of Investigations
  The Bureau of Mines conducted an investigation into the occurrence of outbursts of salt known to be responsible for explosions, fatalities, and damage in domal salt mines. The purpose of the investigation was to develop a basis for predicting these outb...
• Gas Content Determinations of Salt Samples Using Acoustic Responses
  1/1/1987 - Reports of Investigations
  The Bureau of Mines has developed a practical methodology for determining occluded gas contents of domal rock salt samples. The method, which is portable and fieldworthy, provides results in 5 min or less.
• Methane Content of Gulf Coast Domal Rock Salt
  1/1/1984 - Reports of Investigations
  This report considers the results achieved when 80 domal salt samples were tested for gas content by dissolution in a controlled atmosphere chamber.
• Assessment of Methane Hazards in an Anomalous Zone of a Gulf Coast Salt Dome
  1/1/1984 - Reports of Investigations
  This Bureau of Mines research study found gas emission rates from an advancing face, and flows and pressure of gas from an exploration drill hole were dependent upon the geology of salt encountered in a domal salt mine. This information suggests a great...
• Methodology for Determining Occluded Gas Contents in Domal Rock Salt
  9/1/1982 - Reports of Investigations
  The Bureau of Mines has developed two experimental designs for determining the volumes and relative proportions of the various gas species, particularly methane (CH4), occluded in rock salt. The two methods are ball- mill crushing and dissolution. Of th...
• Investigation of Methane Emissions From an Advancing Face in the Belle Isle Domal Salt Mine, Louisiana
  1/1/1982 - Reports of Investigations
  The Bureau of Mines measured methane emission rates from an advancing salt face ranging from 15 to 56 ft3/ton (0.5 to 1.8 M3/t). Small room size, use of a continuous miner, and a well-defined ventilation system made possible air velocity and methane con...
