Dangerously high stress areas can be controlled by proper mine planning and/or destressing. This paper reveiws practical methods to detect and destress high-stress zones along coal faces. The U.S. Bureau of Mines investigated stress-related burst problems and destressing efforts at a cooperating mine. Laboratory tests of the drilling yield method for high-stress detection were conducted to determine the correlation between the volume of cuttings obtained and the magnitude of the applied stress. A three-dimensional computer modeling program was used to evaluate the effectiveness of stress relief methods.
