During the construction of advanced drilling or geological structure exploration drilling in the underground floor of the mine, complex situations including falling block sticking, shrinkage, hole collapse and water inflow occur from time to time. After summarizing and analyzing the causes of complex situations in the hole, this paper gave a reasonable and accurate judgment. According to the judgment results, targeted measures were formulated to minimize the probability of occurrence of complex situations or accidents in the hole and minimize the harm.
