摘 要: | 根据对华北型煤田剖面、平面和水力内边界的水文地质特征的系统综合分析,本文首次提出了煤矿吉立体充水地质结构的新理论。同时,依据风边界在空间展布的几何形态特征,将其划分为四种基本类型,即点状岩溶陷落柱型内边界,线状断裂(带)、裂隙型内边界,窄条状隐伏露头型内边界和面状裂隙网络(局部面状隔水层变薄区)型内边界。根据四种基本类型的不同形式,介绍了煤矿井不同的复合内边界类型和它们的矿井水文地质特征。文章最后

Abstract: | This paperputsfirstly forw ardsa new theory aboutstereo water-filled structuresform inesin the coalbasinof North China, on the basis of com prehensive, analyses of hydrogeologicalfeatures as view ed from cross-sections,plans and innerhydraulic boundaries ofthe basin. Meanwhile, fourtypes ofthe basic innerhydraulic boundaries havebeen divided in thisstudy according to extending geom etricshapesofthe innerboundariesin space. They arerespective-ly considered aspointkarstcollapsecolum n, linearfault(fracture)zone, narrow buried outcrop zone, and planarfissurenetwork in aquitard. Thepaperaiso introducesvarioustypesofcom pound innerboundaries, which consistoffourbasicones with theirm ine-hydrogeologicalcharacteristics. Finally thispaperconcludesthattheinnerhydraulicboundariesarethoughtto bea kernelofthe stereo water-filled structure, and thatprofound research on the innerboundaries is a keyfor solving m ore and m ore seriousw aterhazardsin them inesofthe coalbasin. |
