Select the correct order with respect to the core sizes
Answer & Solution
Correct Answer:
Option
B
The correct answer is Option B: NX > BX > AX > EX.
Here's why:
These codes (NX, BX, AX, EX) refer to standard core sizes used in core drilling during mineral exploration and geotechnical investigations.
They represent the diameter of the rock core retrieved from the drill hole.
The letters are in a roughly descending order of size.
* NX core is the largest of the given options.
* BX core is smaller than NX.
* AX core is smaller than BX.
* EX core is the smallest of the given options.
Therefore, the correct order from largest to smallest core size is NX > BX > AX > EX.
