Abstract:

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.
