RMR and Q system are rock mass classification systems used in geology to evaluate the stability of rock slopes and tunnels.

• RMR stands for Rock Mass Rating and Q system stands for Quartzite Rating System.

• RMR uses six parameters including uniaxial compressive strength, rock quality designation, joint spacing, joint condition, groundwater conditions, and orientation of discontinuities.

• Q system uses three parameters including the quality of the rock mass, the stress conditions, a...read more

• Examples of routers include Cisco, Netgear, and TP-Link

Various methods can be used to draw 3D mapping, including photogrammetry, LiDAR, and ground-penetrating radar.

• Photogrammetry involves taking overlapping photographs from different angles and using software to create a 3D model.

• LiDAR uses lasers to measure distances and create a 3D point cloud of the area.

• Ground-penetrating radar uses electromagnetic waves to detect changes in soil or rock layers and create a 3D image of the subsurface.

• Other methods include sonar, satellite im...read more
