Laboratory evaluation of shear strength properties for cement-based grouted coal mass

Published in Arabian Journal of Geosciences

Cement-based grouting has been widely used in underground coal mining to improve the overall quality of highly fractured rock masses. Due to the difficulties in obtaining characteristic specimens from highly fractured coal rocks, there are very limited laboratory studies investigating the effect of grout on the strength of coal. The purpose of this...
