摘要
尧峪金矿区超厚水敏性风化层,在钻进过程中遇到坍塌、掉块、事故频繁发生等问题,采用常规护壁措施并没有取得预想的效果。通过试验应用PAB不分散聚合物泥浆和钾基处理的聚合物泥浆,取得了良好的效果,顺利完成了ZK604孔的钻探施工,为该矿区今后的钻探工作提供了一些可供参考的经验。介绍了该矿区钻探施工的难题以及采取的泥浆技术措施。
Because of the extremely thick water sensitive weathered layer in Yaoyu gold mine, collapsing and block-falling occurred frequently in drilling process, and the common wall protection measures were not effective to deal with the acci- dents. ZK604 was completed by experimental application of PAB non-dispersion polymer mud and potassium polymer mud. The paper introduces the difficulties and the relative mud technologies in the drilling construction of this mine.
