During the construction of the cylinder inspection hole, the main aquifer is stratified pumping test, which needs to be carried out many times, and the operation of the pump casing, which increases the difficulty of the construction of the hole in the wellbore.In order to solve this problem, through the Tashidian area a number of mine main, auxiliary shaft check of hole construction process of pumping casing sticky cards, falling off accident treatment scheme were analyzed and summarized, put forward a series of treatment and prevention measures, provide certain reference for the future similar project construction.
