New Insights of Grouting in Coal Mass: From Small-Scale Experiments to Microstructures
Pre-grouting as an effective means for improving the stability of roadways can reduce maintenance costs and maintain safety in complex mining conditions. In the Guobei coal mine in China, a cement pre-grouting technique was adopted to enhance the overall strength of soft coal mass and provide suffic...
