COMPONENTES DEL MRMR (2000)<br />

• IRMR = P(BS) + P(JS) + P(JC)<br />

P(x)<br />

• Es el puntaje asociado al parámetro x.<br />

BS (Block Strength)<br />

• Es la resistencia en compresión uniaxial <strong>de</strong> los bloques <strong>de</strong> roca que conforman el macizo<br />

rocoso; la cual <strong>de</strong>pen<strong>de</strong> <strong>de</strong> la resistencia <strong>de</strong> la roca “intacta” (<strong>de</strong>nominada IRS, Intact Rock<br />

Strength, en el método <strong>de</strong> <strong>Laubscher</strong>), y la presencia <strong>de</strong> vetillas. El puntaje asociado a BS<br />

pue<strong>de</strong> variar <strong>de</strong> 0 (si BS = 0 MPa) a 25 (si BS ≥ 160 MPa).
