According to barton(1974) the quality of a given rock mass can bedetermined using the equation below. explain each of the parametersin the equation is obtained.

Q = RQD/Jn * Jr/Ja * Jw/SRF

where;

RQD = drill core quality

Jn = number of joint sets

Jr = joint roughness coefficient

Ja = joint alteration number

Jw = degree of water seepage

SRF = stress reduction factor
