In-situ test and bolt-grouting design evaluation method of underground engineering based on digital drilling

The reasonable design and in-time optimisation of the supporting scheme is very important for ensuring the safe control of the surrounding rock. The key steps are to conduct in-situ real-time tests and quantitative evaluation of the surrounding rock before and after being supported. In order to solv...
