Research of Water-Rich Marl Grouting Technology of DongQu Roadway

Based on a roadway project of Dongqu Colliery of Xishan Coal and Electricity Group,using the geological exploration data and on-site research and referring to the theory and engineering experience, the tunnel grouting program for marl was worked out and it was revised the program in the construction. A method of grouting for soft rock in roadway construction was summarized ,getting a good results and verified by numerical simulation.
