compressing of the roof strata between the hardened resin 29 and the plate 23 as generally indicated in fig5 the 34 fully grouted 34 bolting method involves providing a sufficient quantity of resin 29 entirely to fill the space above the upper end of the bolt and the annular space 39 along the entire length of the bolt to secure the bolt throughout its length in the bore 27 this effects bonding or pegging of the roof strata along the entire length of the bolt 5 in the bore 27 once the resin has hardened the nut 7 may be rotated for high pressure engagement of plate 23 with the roof surface 25 to provide a greater roof support force than is possible with the prior art 34 fully grouted 34 bolting method in which there is no rotation of the nut after the hardening of the resin a simultaneous 34 point anchored 34 and 34 fully grouted 34 bolting method is illustrated in fig6 this involves inserting a quantity of fast setting resin 29a and subsequently inserting a quantity of slow setting resin 29b like 34 fully grouted 34 bolting the total quantity of resin both fast setting and slow setting is sufficient completely to fill the space around the bolt in the bore and as in 34 point anchoring 34 bolting the nut 7 shall be rotated into high pressure engagement.
