Abstract

The utilization and grouting reconstruction of the TOL were applied to working face #3105 of Sangshuping Coal Mine, Hancheng, China. Safe mining was realized without dewatering, and approximately 450,000 tons of “idle coal reserves” that were once seriously threatened by the Ordovician limestone aquifer were emancipated. The successful case study verified the importance of understanding the water-bearing and water-resisting properties of the TOL and proved the reliability of the proposed integral technical system in the utilization and grouting reconstruction of the TOL.
