Abstract
Abstract
| Examples are presented in which Time Domain Reflectometry (TDR) was employed to locate deformation of rock masses induced by mining. The first example involved motoring the propagation of overburden fractures above a longwall coal panel and the second example involved the we of a)R to monitor rock mass deformation in the vicinity of a strip mine highwall. Bock mass deformation, strata separation and large block movement generated strains and failure along coaxial cables which were installed in drill holes and the TDR reflections generated by these strains and failures were monitored. Analysis of field data and a preliminary laboratory test indicate that it may be possible not only to locate rock mass movements but also to quantify these movements with TDR data. |
