谢桥矿8槽煤巷高性能锚杆支护实践

he geological conditions of Xieqiao coal mine road is complex，so decided to make experiment of Anchor Belt support in the Layer-8 in xieqiao mine coal and gob-side entry retaining. This article has formed a high presress, high-strength, high stiffness of the \\\\\\\\\\\\\\\"three high\\\\\\\\\\\\\\\" as the main anchor bolts to strengthen the control theory. including strengthen of bolt support、the breakdown of roadway surrounding rock strength enhancement and the surrounding rock bearing structures. By analyzing the pre-stressed layered roof structure. Pretension supporting structure and the supporting structure to determine the structure of the materials, the development of the M-type strip and the \\\\\\\\\\\\\\\"three high\\\\\\\\\\\\\\\" pretension bolt-based control system technology. The support effect of this coal road is super perfect，the experiment gets tremendous success and the economic benefit is remarkable， A large distance, high-performance pre-stressed rock bolting control technology, has made technical and economic advantages of the great, to meet face to promote a long two-span support requirements meanwhile, the technology of Anchor Belt sup-port is popularized in Xieqiao coal mine.
