induced fracture
Fracture formed in a roof bed as a result of mining operations. For example, on longwall faces fractures are formed in a shale roof parallel to and along successive lines of face. They are induced after coal cutting and become intensified at the end of the loading shift. The distance between the fractures coincides, roughly, with the depth of cut.
