Question

Match the following: 

List-I (Boring Methods)		List-II (Field Conditions)
(A)	Auger Boring	(I)	Below water table in all soil types except hard soils and rocks
(B)	Wash Boring	(II)	Large diameter bore holes over 150 mm in size
(C)	Percussion Drilling	(III)	Exploration for shallow foundations and highways
(D)	Rotary Drilling	(IV)	Bouldery and gravelly strata

The correct answer is:

• A. \(A-III,\;B-I,\;C-IV,\;D-II\)
• B. \(A-I,\;B-II,\;C-IV,\;D-III\)
• C. \(A-II,\;B-III,\;C-IV,\;D-I\)
• D. \(A-III,\;B-I,\;C-II,\;D-IV\)

Hint:

Remember:
• Auger boring $\rightarrow$ Shallow exploration.
• Wash boring $\rightarrow$ Below water table.
• Percussion drilling $\rightarrow$ Gravel and boulders.
• Rotary drilling $\rightarrow$ Deep and large diameter boreholes.
