  • 化学注浆在极破碎围岩支护中的应用……马印禹,熊庭永*,李旭光,王九存,孙飞
  • 摘 要:针对抱伦金矿310 m竖井车场运输巷围岩冒落问题,先采用化学注浆进行预加固,然后再进行“U型钢+水泥砂浆砌碹”。介绍了化学浆液加固和充填高分子材料及注浆器具,重点叙述了断层破碎段巷道和顶板冒落区修复加固及车场超前预加固的注浆施工技术。现场工业试验表明:采用化学注浆进行预加固,可以有效保证支架架设时工作人员的安全,具有极大的推广意义。

    Application ofchemical grouting to the support of extremely fragmented surrounding rocks……Ma Yinyu,XiongTingyong,Li Xuguang,Wang Jiucun,Sun Fei

    AbstractThe solution ofpre-reinforcement with chemical grouting prior to "U shaped steel+archbuilding with cement mortar" is used to treat the surrounding rock cavingin the vehicle yard at the 310 m vertical shaft in Baolun Gold Mine.The paperintroduced chemical grouting reinforcement,high polymer material filling andgrouting instruments,emphatically described the grouting implementationtechnology of the reinforcement of fault and fracture roadway and roof cavingzone and the in-advance pre-reinforcement of the vehicle yard.Field industrialtest shows that chemical grouting for reinforcement can effectively ensure theoperators safety when thesupport is set up.The technology has great promoting significance.
