Role & responsibilities 1. Daily drilling planning: Prepare shift-wise drilling schedules in coordination with the Mining In-charge and SECL team. Allocate drills, operators and helpers according to bench readiness and production requirements. 2. Hole marking and spacing discipline: Verify hole positions, first-row alignment, burden, spacing and drilling boundaries against the approved layout. Coordinate with survey and SECL personnel to resolve discrepancies before drilling. 3. Depth and alignment accuracy: Ensure drilling follows the prescribed hole depth, diameter, inclination and approved sub-drilling requirements. Check actual drilled depth and identify short holes, excessive drilling and alignment deviations. 4. Drilling quality control: Monitor collar condition, hole cleaning and hole protection. Identify collapsed, blocked or water-filled holes and report corrective work required before handover. 5. Operator supervision: Supervise drill operators and helpers, allocate work, maintain shift discipline and provide practical guidance on accurate drilling and proper equipment handling. 6. Equipment monitoring: Supervise DTH and excavator-mounted drilling equipment, such as EA-20 or equivalent. Coordinate with maintenance personnel regarding drill, compressor, hammer, rod and bit problems. 7. Productivity and cost control: Track holes completed, metres drilled, productive hours, downtime and re-drilling. Monitor fuel and drilling consumables, identify avoidable losses and improve equipment utilisation without compromising safety or quality. 8. SECL coordination and hole handover: Maintain hole numbering and drilling records. Communicate actual depths,



wet-hole conditions, obstructions and deviations to SECLs blasting personnel before handover. 9. Post-blast feedback: After authorised clearance, review fragmentation, toe formation and oversized boulders with the mining and blasting teams. Record drilling-related observations for improvements approved by the responsible technical personnel. 10. Safety and reporting: Enforce applicable mine safety requirements, site SOPs, PPE use, dust control, safe equipment movement and exclusion-zone discipline. Stop unsafe work, report hazards and submit accurate daily drilling and shift-handover reports. Technical skills
- Practical knowledge of DTH blast-hole drilling, excavator-mounted drills and compressors.

- Previous work at SECL or other Coal India subsidiary projects, including MCL, CCL or NCL, preferred.
- Experience with mining contractors or mine developer and operator companies.
- Exposure to bench drilling, hard-rock OB conditions and coordination between drilling, blasting and excavation operations. Education and qualifications
- Diploma in Mining Engineering preferred.
- ITI or Diploma in Mechanical Engineering with strong relevant drilling experience may also be considered.
- B.
E./B.
Tech in Mining Engineering candidates with suitable field experience are welcome.
- Relevant coal-mine competency certification is an added advantage; qualifications must match any statutory duties assigned.
