The graphs (a), (b), (c), (d), and (e) show the functions of RQD, span, area, height, and buried depth, respectively.
For the quartz mica schist the average uniaxial compressive strength (UCS) is 54 MPa, the average RQD is 42%, joints spacing range from 200mm to less than 60mm, joints encountered are rough to slightly rough and, are unweathered, joint persistence range from less than 1m to 10m, and joint apertures range from 0.1mm to 5mm in width filled by hard and soft filling materials.
Rock Quality Designation (RQD) index was developed by Deere (1963).

The survey was performed by taking a control sample every 25 centimetres; rock quality designation (RQD), however, was defined by homogeneously fractured sections.
The 919 metres of diamond core collected has been geologically logged, photographed and rock quality designation (RQD) measured on the oriented core.
