The complex hydrogeological conditions in China coalmines have created a number of inherent water hazards. In the over 60 years of efforts in water hazards control, rich experiences have been accumulated in technology engineering. This article focuses on the major development stages and illustrates current applications of the key technologies in hydrological drilling, grouting and water plugging, and geophysical and geochemical prospecting, as well as the direction for future development, which can provide reference and facilitate communications with coalmines under similar conditions across the world.Keywords

Pore aquifer water is one of the major hazards in China’s coalmines, causing severe pit flooding and human casualties. This article analyses the two types of water conduits, pre-existing and man-made, that are culpable to water-sand inrush when mining undertakes in pore aquifers. It also describes four patterns of inrush mechanisms: 1) water-sand inrush when mining-caused caving zone and water-conductive fissures channelling pore aquifer through pre-existing conduits, such as water-conductive faults;2) water-sand inrush when mining-caused water-conductive fissures channelling pore aquifer; 3) water-sand inrush when mining-caused caving zone channelling pore aquifer; 4) when mining undertakes in steeply inclined coal seam, the water-resistant coal pillar caves and leads to water-sand inrush. This article has also studied the effect of the particles size distribution of pore aquifer on the rheological properties of water-sand by permeation tests. The purpose of this review is to concisely summarize and provide references for countries confronting similar problems and to facilitate international discussions on pore water control.Keywords

Major ions, trace elements and isotope concentrations were measured in water samples collected from Ordovician limestone aquifer and surface rivers in Suxian coal mine district, China. The geochemical characteristics and hydrochemistry process were discussed, and serious results could be obtained: Groundwater samples from Ordovician limestone aquifer were mainly the Na-SO4 and Na-HCO3 types, the similar feature with the river water samples suggesting a certain relationship may be existed between groundwater and surface river water. The total REE concentrations (ΣREE) in groundwater samples varied from 0.0263 to 0.1348 mg/L, with an average value of 0.063 mg/L. The oxidative conditions are the mainly factors deduced the negative Ce anomalies and positive Eu anomalies. The groundwater samples, recharged by the precipitation and surface water, have lower concentrations of δ18O and δD comparing with river water, reflected the river water affected by the evaporation clearly, with the heavy isotope enrichment. The negative correlation between δ18O and TDS and Ca2+ indicated that the dissolution of limestone could be the factor influencing the oxygen isotope characters. Groundwater in Ordovician limestone is runoff from both sides to intermediate, with the Taoyuan coal mine as the subsidence center in study area, evidenced by the contour diagrams of TDS and δ18O. The hydrochemistry field and runoff field of groundwater in study area are mainly controlled by the tectonic field, especially the Sunan syncline.Keywords
