This paper describes a rock mechanics instrumentation program, data analyses, and a comparison of two case studies conducted at two underground mines, designated as "a" and "b", in the Illinois coal basin. The instrumentation plans and data collected during development and long-term monitoring of four-way intersections and adjoining entries are presented. Data analyses of premining and postmining roof stress, pillar loading, strata movement, roof bolt loading, and geologic features are included.
