Description:Cable bolts are emerging as the newest twist for roof support in U.S. underground coal mines. For decades cable bolts installed in underground metal mines in the United States and Canada used cement-based grouts for anchoring. The cement anchoring process, because of the time and expense for installation, made cable bolts impractical for use in coal mines. Today, the introduction of resin-anchored cable bolts provides a system more consistent with tradi tional U.S. coal mine roof bolting practices and requirements. Expecta tions are that the utilization of cable bolts for a number of U.S. mining applications will expand, particularly in coal mining.
