Water-Bearing and Water-resisting Properties of Top of Ordovician Limestone in North China Coalfielerties of the TOL in NCCs. The comprehensive evaluation method of the water abundance of TOL in coal mining areas was presented. Three vertical zones in the TOL were put forward, which set the foundation for field implement of utilization and grouting reconstruction of the TOL.作者: 拘留 時(shí)間: 2025-3-22 18:58
