Abstract
The integrity factor approach was developed by the U.S. Bureau of Mines to assess the stability of mine pillars and has been applied primarily to longwall chain pillars. Recently, this approach was applied to a room-and-pillar mine in the Illinois Coal Basin. A special configuration of hydraulic borehole pressure cells was installed in a pillar to determine the in situ strength-and-stress relationship of the coal pillar and to verify the applicability of the integrity factor approach. Results indicate that the integrity factor approach is applicable to the assessment of pillar stability and may be a realistic and effective approach for room-and-pillar mine design.
