Abstract
"A three-phase test program was utilized to evaluate some creep and stiffness parameters of several types of full-column resin-grouted roof-bolt installations. The tests indicate that: (1) a large percentage of an applied load bleeds off during the first 100 hours subsequent to bolt installation; (2) the amount of load bleed-off is a f unction of the grout annulus size and the bolt surface roughness; (3) retightening of grouted rock bolts reduces the magnitude and rate of the load bleed-off phenomenon; and (4) resin-grouted roof bolts provide a stiffer roof support system in that bolt elongation resulting from an applied load, e.g., geologic post- tensioning due to strata movements, is much less than for mechanically anchored systems"-- Abstract, p. iii
