Abstract North China is the main coal producing area in China.Ordovician limestone aquifers are widely distributed, karst fissures are strongly developed, and floor water disasters occur frequently under pressure mining conditions. The existing prevention and control technology has the problem of insufficient regional adaptability. Taking Dongpo Coal Mine, a typical mine in North China Coalfield, as the carrier, combined with the characteristics of regional hydrogeological zoning, an Ordovician limestone water disaster prevention and control technology system suitable for North China was constructed. The three-level comprehensive geophysical exploration combination of ' macro-control boundary-meso-positioning-micro-qu-
alitative ' was optimized, targeted drilling verification technology was innovated, a three-in-one monitoring network of ' up-hole-underground-in-hole ' was established, and grouting materials and processes were developed which were suitable for high salinity and high water pressure environment in North China. The application results showed that the unit water absorption of strata after injection was 94.7 % lower than that before injection, which ensured the safe mining of No.924 Face. The system had good adaptability in mines with similar hydrogeological conditions in North China, and provided a universal scheme for regional Ordovician limestone water disaster prevention and control.
