What does RQD mean in MILITARY
RQD stands for Rock Quality Designation. It is used by geologists and rock engineers in the field of mining engineering to evaluate the quality of rocks that are in contact with the surface, or underground. It assesses various parameters including hardness, joint spacing, jointing trends and structural features that can affect rock stability and integrity. The RQD index has become a standard tool for designing safe, stable hard-rock mines since its introduction 50 years ago.

Definition
Rock Quality Designation (RQD) is used by geologists and rock engineers to assess the overall characteristics of rocks exposed at or near the ground surface. It utilizes a numerical score from 0 to 100 to quantify rock quality based on variables such as joint count and pattern, block size, attitude of fractures or strata relative to each other, degree of weathering or alteration of the rock, fissility (ability to split along a plane), and other structural parameters that can influence how stable a particular piece of rock is when subject to stress or strain.
Process
The process of determining RQD involves first surveying the area being studied before taking core samples at regular intervals across it. Core samples are then subjected to examination in order to determine their qualitative attributes such as block size and shape, joint spacing and orientation, fissility (ability to split along a plane), weathering/alteration etc., In addition visual inspection may be done where fracture planes will be noted down if visible at surface level. All these observations are put together into a composite score between 0-100 which gives an indication as to how well represented the rock types are instantly from surface level.

Final Words:
By understanding RQD values geologists can access both potential mining hazards like fault zones as well as identify more homogenous material suitable for efficient mining operation while tackling geological challenges such as open pit depths or tunnel sizing. Consequently this index serves as an essential mining parameter helping engineers understand site conditions before commencing work and design structures capable of withstanding environmental forces acting upon them during operational timespan.
