Rock Mass Classification is the first app ever that gives an easy-to-use tool to calculate the four most important things about rocks, namely - Rock Quality Designation (RQD), Rock Mass Rating (RMR), Tunneling Quality Index (Q), Geological Strength Index (GSI)

This 4-in-1 tool can make a miner's/geologist's life much easier. Forget about bulky huge charts and calculators and tons of confusion. RMC can do your job in a jiffy. Fire up the app, select a few check-boxes and boom! You have got the result.
