摘要
彬长矿区白垩系洛河组砂岩含水层是威胁矿井安全的主要充水含水层。为了查明其水文地质条件,采用地面与井下钻探、水文测井、抽(放)水试验、水化学测试、岩样测试及水文长观等手段进行探查与研究。结果表明洛河组含水层可分为上、下两段。洛河组含水层上、下段在地层厚度、岩性、富水性、水文地质参数、水质、水温等方面存在显著差异。
The Cretaceous Luohe formation aguifer in Binchang mining area was the main water-filled aquifer that threatens mine safety.In order to ascertain its hydrogeological conditions, exploration and research were conducted by means of surface and downhole drilling, hydrological logging, pumping （releasing） water test, hydrochemical test, rock sample test and hydrological observation. The results show that Luohe formation is divided into upper and lower sections. The upper and lower sections have significant differences in stratum thickness, lithology, water-richness, hydrogeological parameters, water quality and water temperature
