Abstract:
A sinkhole formation detection system includes tension members associated with sensors. The tension members are arranged in a horizontal grid in an overburden, and each of the tension members is under a longitudinal tension. The sensors are each for generating outputs in response to changes in the longitudinal tension of one of the tension members in response to a vertical displacement of the overburden.
