Abstract
The shear head device includes a monitoring head having geophones and transmitters inside a cylindrical body. A shear head is coupled to the monitoring head from below. The shear head has a tubular structure with a plurality of apertures formed around an outer surface of the tubular structure. A plurality of cones are coupled with modified tips and disposed within the plurality of apertures. A sheet supports the plurality of cones inside the shear head. The sheet is selectively movable between a first radial position and a second radial position for the modified tips to apply radial force to the rock by adjustment of an internal pressure of the shear head. The transmitters transmit the recorded acoustic emission to a computing system for determining properties of the rock while the shear head device is testing the rock in the bore.
