摘要
Drilling in complex strata will encounter instant uncertain issues such as cave-in, rock fall, gushing water (leaking), necking, etc., which may lead to discontinuity of construction without careful plan and timely treatment. This paper, based on experience in construction in a mine, probed into successful doings, reviewed remaining issues to avoid their reoccurrence.
