摘要
分析了现行锚索锚具在现场应用中存在的问题,提出了研制新型锚索锚具—球型锚具的思路,并研制出了KM18型球型锚具,通过地面试验室试验和在煤矿掘进工作面试验,得出了结论。
The problem in field application of anchorage cable was analyzed.The idea of a new anchorage cable-spherical anchorage cable was given.And a new spherical anchorage cable KM18 was made out.After application in ground lab and coal mine digging working face,the results were enduced.
