摘要
通过对镇城底矿GS13-2水文孔出水经过、突水原因的分析,提出适合井下带压水文钻孔的封堵治理方案,总结了配重计算、止水塞下放、补注浆等技术措施。在此基础上,提出了水文钻孔设计与施工等方面的合理化建议,为同类钻孔的施工、日常监管与应急封堵提供了借鉴。
By analysing the process and the cause of the water inrush of GS13 - 2 hydrological hole in Zhenchengdi coal mine, puts forward the plugging solution to suit for underground hydrological drilling with pressure, summarizes technical measures such as weight calculation, installing sealing plug, filling grouting and etc. On this basis offers rationalization proposal on hydrological borehole design, construction and other, for similar drilling construction, daily supervision and emergency plugging provides the reference.
