Abstract
The thesis put forward new understanding on the water-bearing and water-resisting properties of the TOL based on the field investigation in six large mining areas in NCCs, the study on the paleo-sedimentary environments of the Ordovician strata and karst development characteristics of the TOL in typical mining areas. The technical thought of “plane partition and vertical zonation” was applied to evaluate the lateral water yield property and the vertical zonation of the TOL. The major difficulties related to grouting reconstruction in the TOL were studied from a holistic aspects including grouting material proportion experiments, dispersion mechanisms of grouting materials, grouting system optimization, and development of automation control software. An engineering case study was carried out in Sangshuping Mine of Shaanxi Coal and Chemical Industry Group.
