The mining bolt is also comprised of a flange system disposed about the shaft in proximity to one end thereof such that when the shaft is threaded into the rock, the flange system abuts under tension the rock's face. A method for holding rock in a mine comprising the steps of drilling a bore hole into the rock; and inserting the shaft of a mining bolt into the bore hole. The shaft has a flange system disposed about the shaft in proximity to the end thereof. The shaft has threads and is of a length longer than the length of the bore hole. There is also the step of screwing the shaft into the rock at the top of the bore hole such that the threads of the shaft penetrate into the rock and the flange abuts under tension the rock face.
