Volumetric Joint
correlatıon rqd – volumetrıc joınt count
The 3-dimensional block volume Vb and the volumetric joint count Jv measurements give much better characterizations of the block size. As the block size.
1982
The volumetric joint count Jv is a simple measure of the degree of jointing. It takes into account all the occurring joints and fractures and is easily calculated.
