Deep Well of Coal Roadway Bolt-Cable Mechanism Analysis and its Engineering Application

Abstract

Cable Anchor Supporting mechanism theory analysis, combined with high geostress, composite roof and complex geological conditions, the deep well under conditions of coal roadway by small aperture, anchor on the form of the structure and high prestressed construction technology, engineering practice shows that the technology is simple and applicability,is deep well solve the high stress soft rock tunnel, large sections into bifurcation point supports of the effective way of the problem. Not only reduces the support cost, reduce the workload of the Lane repair, and also greatly reduce the labor intensity of construction personnel, improve the reliability of the engineering safety. Accumulated experience, has broad application prospects for the deep well under the conditions of the other coal mine soft rock roadway
