Praktyczne zastosowaniaKlasyfikacji w Górnictwie

• M-RMR (Laubscher and Taylor, 1975)
• Mod.RMR (Newman and Bieniawski, 1981)
• MBRMR (Cummings and Kendorski, 1982)
• Coal Mining RMR (Unal, 1983)
• Indian Coal RMR (CMRS, 1986)
• Coal Mine Roof Rating (Molinda and Mark, 1994)
• Weak Rock RMR (Unal, 1996)
• Deutsche Steinkohle klasifikacion (Witthaus,
  2006)

Conclusions

• Place rock mass classifications within the
  overall engineering design methodology and
  process
• Observe the Ten Commandments for use of rock mass
  classifications
• For best engineering practice, exchange
  experience between tunnelling and mining
  projects.
