Pretension determination and application of entry's roof anchor cable
by studying the mutual action between roof anchor bolts(cables) and surrounding rock, it is pointed out that the anchorcable's pretension is the key to the entry support. Based on the principle of anchor cables, theentry's roof is treated as an clamped beam to calculate the pretension of an anchor cable. The research results have reference value for cable pretension determination in engineering practice.
