Study on the Failure Height of Overlying Strata in Shallow Seam with Thick Bedrock
Abstract:
It was very important to obtain the failure height of overlying strata to ensure safety mining under water body and protect surface and underground water resources. Aimed at the failure of overlying strata of 6204 full-mechanized mining in Ordos, the paper proposed a new detection method of the failure height of overlying strata, and verified the accuracy and practicability of this detection method by comparing with the traditional borehole TV observations.
