Calculation of anchor parameters at the wide road lining
Based on the theory of bending of beams on elastic foundation the task is being solved for the determination of suitable parameters of anchors in wide (above 8 m) workings. It is suggested to support the roof in two tiers - with short and long anchors - taking into account finding the parameters of long anchors (basic) the bearing capacity of rock layers of immediate roof sewn with short anchors into a bundle.
