Ground Stress in Mining (Part 1): Measurements and Observations at Two Western U.S. Longwall Mines

NIOSH researchers have been conducting research with the goal of gaining a better understanding of ground stress redistribution resulting from mining. Part 1 of this research, reported here, involves representing stress redistribution using empirical equations or numerical models that are calibrated to observations and measurements. In Part 2 of this research, numerical models are used to calculate ground stress in mines.
