Choosing the right borehole drilling method is important. It affects water quality, drilling cost, and how long the borehole lasts. Each method suits a specific type of soil, rock, and water table. Before drilling, it is good to understand the different methods and which one works best for your location.
Understand Your Ground Conditions
The type of soil and rock under the ground decides which drilling method will work best.
Soft soil such as sand or clay is easy to drill through, but it may collapse without support. Hard rock like granite or volcanic rock is stable but difficult to drill. Some areas have mixed ground – soft on top and hard below. A geological survey helps know what lies underground before you start.
Common Borehole Drilling Methods
Each drilling method works better in specific conditions. The four most common ones are percussion, rotary, down-the-hole (DTH), and manual drilling.
1. Percussion Drilling
Percussion drilling uses a heavy bit to hammer down into the ground. It breaks soil or rock by repeated impact.
Best for: Soft to medium ground
Advantages:
-
Simple and affordable
-
Uses little water
Disadvantages: -
Slow in deep or hard rock
-
May need casing to avoid collapse
2. Rotary Drilling
Rotary drilling uses a rotating drill bit to cut through the ground. Drilling mud is pumped down to bring cuttings up.
Best for: Deep boreholes in soft and mixed soil
Advantages:
-
Fast and efficient
-
Works in different soil types
Disadvantages: -
Requires drilling fluid
-
Higher cost than percussion
3. Down-the-Hole (DTH) Drilling
DTH drilling combines rotary motion and percussion. The hammer is located just behind the drill bit.
Best for: Hard rock areas
Advantages:
-
Very fast in hard ground
-
Makes straight holes
Disadvantages: -
Needs skilled operators
-
Equipment is more expensive
4. Manual Drilling
Manual drilling is done by hand with simple tools. It is used where machines cannot reach.
Best for: Shallow wells in soft soil
Advantages:
-
Very low cost
-
Can be done in remote places
Disadvantages: -
Only works in soft soil
-
Not suitable for deep boreholes
Factors to Consider When Choosing a Method
Before choosing, look at these key points:
1. Depth of the Borehole
If the aquifer is deep, you need a fast method like rotary or DTH. Manual and percussion work well for shallow depths.
2. Type of Ground
Soft soil needs support during drilling. Rotary with mud or casing works well. Hard rock needs DTH for speed and precision.
3. Water Needs
If the borehole will serve many people or a farm, it must be deep and wide. Rotary or DTH methods are better.
4. Budget
Manual and percussion drilling are cheaper. Rotary and DTH cost more but give better results in tough conditions.
5. Site Access
Some areas are too narrow for big machines. Manual or portable rigs may be needed in such places.
