Roof bolting and stabilisation of natural arches on roadways
Principal function of roof bolts on roofs of unripped longwall goafs is to bind strata together; this enables bolts to withstand lateral forces that sustain them; forces are induced by roof itself as it sags for want of vertical support; forces follow curved path across width of opening and within thickness of bolted part of roof, this forming natural arch.
