Abstract
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 traditional U.S. coal mine roof bolting practices and requirements. Expectations are that the utilization of cable bolts for a number of U.S. mining applications will expand, particularly in coal mining. Because of the coal industry's interest in injury prevention and safety and the potential cost savings, the growth in use and development of cable bolt systems is expected to continue. Some advantages of cable bolts compared to traditional roof supports used in coal mines are detailed below.
