| Abstract: | The principles and measuring method are dealt with for fast estimation of stresses in loosened and broken rock in the paper on the basis of field measurement,lab.Modeling and theoretical analysis. The equation is put forward expressing relationship between amount of drilling and stresses in coal mass, with stress-softening property of unelastic coal area and volume expansion (dilatation) consided. Means of choice of calculation of parameters and practical application are discussed as well,having practically important value. |
