近年来,国内采用长锚索支护采场顶板取得了很大的成功。1981年初,铜陵有色金属公司设计研究院和凤凰山铜矿共同开始应用长锚索支护采场顶板的试验工作;1982年长沙矿山研究院配合公司有关单位进行了长锚索、短锚杆和光面爆破的联合护顶方案的试验研究,确定出了适用于凤凰山铜矿的锚杆、锚索结构型式及参数,研制出了相应的施工工艺和机具。该矿自1981年2月至1983年10月共安设长锚索442根,短锚杆5000根,支护面积1.3万米~2,
In recent years, the domestic use of long cable anchor roof mining has made great success. In early 1981, Tongling Nonferrous Metals Company Design and Research Institute and Phoenix Mountain Copper Mine began the application of long cable support pit roof test work; 1982 Changsha Institute of Mining with the company’s long-term cooperation with the relevant units, short bolt and light Surface blasting joint protection program of the program to determine the suitable anchor for the Fenghuangshan Copper Mine, anchor cable structure types and parameters, developed a corresponding construction technology and equipment. The mine from February 1981 to October 1983 set a total of 442 long anchor cable, 5000 short anchors, supporting an area of 13,000 meters ~ 2,
