1）Process Introduction

Wire line core drilling means that when retrieving the rock core, there is no need to pull out the entire drill string from the borehole. Instead, a hoist and a fishing tool with a wire rope are used to lift the inner tube at the bottom of the hole, which contains the core, to the surface, thus obtaining the core. This can reduce the number of times of tripping the drill and the auxiliary time for raising and lowering the drilling tools, thereby improving the drilling efficiency.
