Tensional behavior of floor bolts in advancing longwall coal mining
In British coal mine considerable trouble had been experienced due to floor "heave"; at distance of between 80 and 90 yd behind face, floor was breaking up and tending to close entry; heave was prevented by bolts which were anchored in strong sandstone beneath thin band of coal; use of load cells to determine bolt tension under various conditions.
