Drilling Strata Movement Detection Experiment on Failure Law of Overlying Strata Movement [PDF]
Proceedings of the Taishan Academic Forum - Project on Mine Disaster Prevention and Control, 2014 The principle and test method of drilling strata movement detection is introduced. The failure law of stope drilling strata movement was analyzed and judged by useing the swell character of compresspoed wood when it met upon the water and moves along with surrounding rock.

Lithosphere, 2022 Abstract Roof movement induced by coal excavation is the immediate cause of rock pressure redistribution and strata behavior. The rigid block in PFC3D was used to generate a multijointed rock mass, and the PFC3D–FLAC3D coupling model was used to study the movement law of the highly developed structural plane of the overlying strata ...

A Case Study of Surface Borehole Wall Dislocation Induced by Top-Coal Longwall Mining
Energies, 2017 Underground coal extraction causes failure and movement of overlying strata, which could also result in the dislocation of vertical surface boreholes. Investigating the correlation between the dislocation of surface boreholes and the broken of overlying ...
