摘要
Abstract
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.关键词
