矿井井筒开拓安全通过巨厚洛河组砂岩含水层是一个普遍的难题,普通水泥注浆法无法形成有效的止水帷幕。为了给地面预注浆或帷幕注浆法过洛河组砂岩含水层提供依据,通过改变注浆材料,开展了超细水泥浆液在洛河组砂岩中的注浆试验研究。通过试验研究,较好地掌握了超细水泥对洛河组砂岩注浆性能,获得了相关的注浆经验。结果表明,超细水泥浆液无法对洛河组砂岩实现可注,并从微观结构上分析了不可注的原因。研究成果对类似地层的注浆改造和井巷工程的安全施工具有一定的借鉴与指导意义,避免了注浆经验导致工程实践的失败与资源浪费。
礦井井筒開拓安全通過巨厚洛河組砂巖含水層是一箇普遍的難題,普通水泥註漿法無法形成有效的止水帷幕。為瞭給地麵預註漿或帷幕註漿法過洛河組砂巖含水層提供依據,通過改變註漿材料,開展瞭超細水泥漿液在洛河組砂巖中的註漿試驗研究。通過試驗研究,較好地掌握瞭超細水泥對洛河組砂巖註漿性能,穫得瞭相關的註漿經驗。結果錶明,超細水泥漿液無法對洛河組砂巖實現可註,併從微觀結構上分析瞭不可註的原因。研究成果對類似地層的註漿改造和井巷工程的安全施工具有一定的藉鑒與指導意義,避免瞭註漿經驗導緻工程實踐的失敗與資源浪費。

It is a universal problem that mine shaft development safely goes through the thick Luohe formation sand -stone aquifer , and the general cement grouting method can't form effective water stop curtain .In order to provide basis for ground pregrouting or curtain grouting method going through Luohe formation sandstone aquifer , by chan-ging the grouting material , the experimental research on the grouting of superfine cement slurry in Luohe formation sandstone was carried out .Through experimental research , the performance of superfine cement grouting in Luohe formation sandstone was mastered bitterly , thus obtaining the relative grouting experience .The results showed that superfine cement slurry cannot be achieved to inject into Luohe formation sandstone , and the reasons were analyzed in the micro-structure .It has certain drawing lessons and guiding significance for similar strata grouting reconstruc-tion and the safety of the mine engineering construction , avoiding the grouting experience leading to failure of engi-neering practice and waste of resources .
