摘要
利用WQCZ-56型围岩强度测定装置在钻孔中进行围岩强度原位测量,该方法适合井下作业环境的需要,测试准确、快捷,测试数据能更好反映原位岩石强度。为巷道支护设计提供可靠的基础参数,具有很好的推广应用前景。
The method of in-situ test of surrounding rock strength in bores with WQCZ 56 strength mensuration instrument is suitable for the need of underground environment. It is precise, fast and its data can be used to reflect better the original strength of rock. It can provide reliable basic parameters for roadway supporting design and have excellent extension and application foreground.
