Abstract
An analytical study of coal mine roof behavior was conducted using a computer model. The room-and-pillar extraction method was used in both the model and in the field. Standard engineering property information was used with a computer code developed for the Bureau of Mines to calculate roof sag, convergence, roof bolt load change, and crack formation and growth. These calculations are compared with experimental data collected during a field investigation involving two test sites, one in a development area and one in the production area of a coal mine.
