澳大利亚中昆士兰煤炭联合公司的克里卡试验矿井,使用装在掘进机上的三台高速液压式锚杆机来支护顶板,已取得成功。 该矿井于1678年9月投产。在井下开拓了五条直达生产煤层的巷道。克里卡试验矿井在某些技术领域方面比较先进。在掘进机上安装三台高速液压式锚杆机就是其中的一例。
The Creamer pilot mine at Midland Queensland Coal Mining Co. of Australia has succeeded in using the three high-speed hydraulic anchor machines installed on the roadheader to support the roof. The mine was put into operation in September 1678. Opened in the underground five directly to the production of coal seam roadway. The kerry trial mine is more advanced in some technical fields. One of the examples is the installation of three high-speed hydraulic anchor machines on the roadheader.
