This article introduces the evaluation of mining conditions under pore aquifer and presents four control techniques on pore water, i.e. retaining safety coal (rock) pillars to resist water, sand, and collapse; draining bottom pore aquifer in Quaternary strata to lower underground water level; presplitting hard overlying rock by blasting to inhibit growths of water-conductive fissures; manually caving the roof strata over the steep sloping coal seam by extruding blast to prevent water-resistant coal pillars from caving. This article is to provide references for countries confronting similar problems and to facilitate international discussions on pore water control.
