Updating the q system for nmt

The Q-system is developed to classify rock masses around an underground opening, as well as for field mapping.Based on estimation of six rock mass parameters, a Q-value for a rock mass can be calculated.All intellectual property rights, including without limitation to copyright and trademark of this work and its derivative works are the property of, or are licensed to, GIGA-BYTE TECHNOLOGY CO., LTD.

The Q-value depends on the underground opening and its geometry, and is therefore not an independent characterisation of the rock mass.The assessment of Tunnel Quality Index “Q” and Geomechanics classification for the granitic rock mass was done based on the information available of the rock joints and their nature and 3D geological logging.

Inadequate BIOS flashing may result in system malfunction.
