    摘要
  • 摘要: 利用覆巖破壞高度觀測鉆孔進行相關測試研究,根據現場鉆孔沖洗液漏失量、鉆孔水位變化以及井下彩色鉆孔電視影像,探明了煤層開采后上覆巖層內垮落帶和導水裂縫帶的發育高度及其分布形態。

     

    Abstract: The vertical boreholes were drilled from the surface for correlation detection of the damage height of overburden rock mass. The expanding height of the inner collapsed zone and the permeable fractured zone as well as their distribution in the overburden rock mass after excavation of the coal seam were determined based on the leakage volume of drilling fluid, the change of water level in the boreholes and the borehole images by color TV.
