- Methane drainage
- Rock slope monitoring
- Connecting two drifts
- Subsidence monitoring
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall the purpose of cross-measure boreholes.
Cross-measure boreholes are drilled from underground roadways into surrounding strata above or below the coal seam.
Step 2: Identify their application. These boreholes are primarily used to drain methane from adjacent strata before it enters mine workings. Hence, \[ \boxed{\text{Methane drainage}.} \] Therefore, \[ \boxed{(A)} \] is the correct answer.
