Mining cable used in coal or other mines, mine, plus rock circles, mine roadway to conventional design bolting forms and parameters, often can not effectively support, resulting in the overall collapse of bolting, have serious consequences. Because steel hinge line length is unlimited, you can anchor ring segment anchor ring on a hard roof, meanwhile, due to higher steel hinge line intensity level can provide a greater prestressed anchor groups in the lower part of the complex roof joint one to form a unified rigid roof, play better supporting effect. Anchor structure generally consists of amplitude anchor head, anchor portion and the outer portion of the anchor head three common components. Within the anchor head, also known as anchoring segment or anchor roots, is to provide anchorage in vivo prestressed rock foundation, its mechanical structure is divided into two major categories, and cementation, cementation style is divided into cement mortar cement and resins categories, and sub-type secondary grouting mortar and grout once-in. Outside the outer anchorage section called anchor head is tensioned anchor in order to provide tonnage and locked position, the type with an anchor plug, threaded, cylindrical reinforced concrete anchor pier, Piers and steel frame anchored so on.
Static load performance parameters, the anchorage efficiency coefficient η.(%)：≥0.95
Total strain when ultimate load §(%)：≥2.0
Anchor rope anti- pulling force TW(KN)：≥165
Plate bearing capacity TB(KN)：≥235
Anchor model ：KM15-1860

Mining anchor rope is made up of steel strand, anchoring agent, tray, anchorage and other of anchoring accessories, through mechanical tension, a device of active pressure of surrounding rock
