• A Hybrid Statistical-Analytical Method for assessing Violent Failure in U.S. Coal Mines
  1/1/1999 - Information Circulars
  This work identified the most important variables contributing to coal bumps. These are (1) mechanical properties of strata, including local yield characteristics of a mine roof and floor, (2) gate pillar factors of safety, (3) roof beam thickness, join...
• Impact of Background Sources on Dust Exposure of Bag Machine Operator
  1/1/1986 - Information Circulars
  The Bureau of Mines has recorded a number of different background dust sources that significantly contaminate the air breathed by bag machine operators. To keep bag operator exposure within acceptable dust levels established by the Mine Safety and Healt...
