Air Rotary Drilling

• Similar to rotary drilling, but uses compressed air to remove cuttings.
• Faster and more efficient than rotary drilling.

Down-the-hole Hammer Drilling

• Uses a pneumatic hammer to break up rock.
• Suitable for softer formations and shallow depths.

Sonic Drilling

• Uses high-frequency vibrations to create a hole.
• Minimal environmental impact and suitable for sensitive areas.

3. How do you ensure the accuracy of shothole placement?

• Use precision GPS equipment to determine drilling coordinates.
• Calibrate drilling equipment regularly.
• Monitor drilling progress and make adjustments if needed.
• Mark shothole locations clearly for later surveys.

4. What safety precautions must be taken when handling and loading explosives?

• Wear appropriate PPE (gloves, safety glasses, dust mask).
• Follow manufacturer’s instructions for handling and storage.
• Secure explosives in a safe and controlled environment.
• Limit access to explosives to authorized personnel.
• Notify authorities immediately in case of any accidents.

5. How do you calculate the appropriate explosive charge size for a shothole?

• Consider depth, diameter, and geological formation of the shothole.
• Use industry formulas and calculations to determine the required charge size.
• Take into account environmental factors (e.g., water table) and safety regulations.
• Verify calculations with experienced colleagues or supervisors.

6. How do you prepare a drilling site for shothole drilling?

• Clear the area of vegetation and any obstacles.
• Mark the shothole location clearly with stakes or flags.
• Set up the drilling equipment and ensure it is stable.
• Create a safe and secure work area for crew members.

7. What are the typical challenges you may encounter during shothole drilling?

• Hard or abrasive rock formations.
• Unstable or soft ground conditions.
• Water table or groundwater interference.
• Extreme weather conditions (e.g., heat, cold, rain).
• Logistical challenges (e.g., remote locations, limited access).

8. How do you troubleshoot common drilling problems, such as bit jamming or slow penetration?

• Check for dull or damaged bits.
• Adjust drilling speed and pressure.
• Clean out cuttings and debris from the hole.
• Verify that the drill rod is properly connected and lubricated.
• Inspect the drilling equipment for any faults or malfunctions.

9. How do you ensure environmental compliance during shothole drilling?

• Follow regulations on soil erosion control and waste disposal.
• Use biodegradable drilling fluids to minimize environmental impact.
• Restore drilling sites to their original condition after completion.
• Report any spills or environmental hazards promptly.

10. How do you stay up-to-date with technological advancements and industry best practices in shothole drilling?

• Attend industry conferences and workshops.
• Read technical journals and publications.
• Participate in online forums and discussions.
• Consult with manufacturers and experts in the field.
