摘要
根据地层含水空间类型,可分为孔隙含水岩组、基岩裂隙含水岩组、岩溶裂隙含水岩组,在施工冲积层、基岩层及岩溶等不同水文孔过程中,对地层地质条件、填砾、下管、洗井作了分析,并论述了在实践中的应用。水文孔钻探与煤田孔钻探既有相同的技术要求,又有不同的工艺流程。
Abstract According to the type of the stratum watery space, can be divided into pore water rock group, the bedrock fissure water rock group, karat fracture water rock group in construction process of different hydrological hole of alluvial layers, bedrock layer and karst etc. , to the stratum geological conditions, filling gravels, low tube, well - flushing carries out analysis and discusses the application in practice. Hydrological drilling hole and coalfield drilling both has the same technical requirements, and has the different process.
