摘　　要：介绍了朱溪矿区ZK1013孔的施工情况。钻孔在470~490、630~650、703~709m三段出现严重坍塌,针对该孔的地层情况。在分析孔壁失稳原因的基础上,提出了两套适用于金刚石绳索取心工艺的复合泥浆体系,取得了良好的应用效果。The construction of ZK1013 hole in Zhuxi mining area was introduced, the severe collapse happened at the sections of 470-491 , 630-650 and 703-709m. According to the formation conditions and based on the analysis on the reasons of the wall instability, 2 sets of composite slurry system suitable for diamond wire line coring process were proposed and good results were achieved.
