Abstract
Chemical grouting has been used to insure the stability of

underground mine openings for more than twenty years. The polyurethane

grout, which is currently being used, has a limited range of mechanical

properties that restrict its utilization. Polyurethane also poses serious

threats to miners' health due to its toxicity and flammability, To overcome

many of these problems and limitations, research has been conducted on a

newly developed polyester-based grout. The assessment of mechanical

properties of polyester grout is the focus of this work. Field experiences and

laboratory research have defined properties which an effective grouting

material should possess. Experimental results indicate that the polyester

grout meets or exceeds these recommended properties and has the potential

to expand the applicability of chemical grouting in ground control. By

adjusting its formulations, mechanical properties of polyester grout can be

engineered to solve specific ground control problems.
