Some investigations into tensional behaviour and influence of bolting reinforcements in mine roadways
Summaries of results of 4 yr of study concerning bolting reinforcements carried out in northern coal fields of Great Britain; investigations at floor bolted site showed influence to be limited to length of bolt; heave was essentially skin effect and bolting effectively eliminated failure; in center of roof of roadway in bedded strata lateral movements occur away from direction of advance; bolts should, therefore, be inclined in this direction.
