Abstract:
The present invention relates to a coring system and a determining method that can determine whether accurate coring was achieved. A coring system according to the present invention includes: a coring part with a core to be filled with an object to be cored; a driving unit controlling upward/downward movement of the coring part; a rope connecting the coring part with the driving unit; and a tensiometer measuring tension in the rope.
