THDC Recruitment 2025: Notification for Mine Surveyor and Junior Overman Posts
Join THDC India Limited, a premier Mini-Ratna PSU under the Ministry of Power - Official Advt. No. 09/2025
THDC India Limited (THDCIL), formerly known as Tehri Hydro Development Corporation Limited, is a prominent Mini-Ratna Category-I Public Sector Undertaking (PSU). While historically renowned for its massive hydroelectric projects, most notably the Tehri Dam, the organization has diversified into various energy sectors, including solar, wind, and thermal power. As part of its strategic expansion into the coal mining sector to support its thermal power initiatives, THDCIL has announced the THDC Recruitment 2025 for technical mining personnel. Under Advertisement Number 09/2025, the corporation is seeking experienced professionals for the posts of Mine Surveyor and Mine Junior Overman in the S-2 Grade for its coal mining projects.
Mining operations require a high degree of technical precision and stringent adherence to safety protocols. A Mine Surveyor is responsible for the accurate mapping and measurement of the coal blocks, ensuring that the extraction follows the designated technical plans. On the other hand, the Junior Overman is a critical safety and supervisory link between the management and the workforce at the coal face, ensuring that production targets are met without compromising safety standards as per the Coal Mines Regulations (CMR). These roles are located in THDC's mining project sites, providing a challenging yet rewarding career path for individuals with the required Directorate General of Mines Safety (DGMS) certifications and hands-on mining experience.
For engineering diploma holders who possess the mandatory competency certificates, this recruitment represents a rare opportunity to join a PSU that offers central government-aligned pay scales and extensive social security benefits. The application process is scheduled to begin on November 7, 2025, and will conclude on December 6, 2025. Unlike general entry-level roles, these positions require a minimum of four years of post-qualification experience, emphasizing THDC's need for "ready-to-work" professionals who can contribute immediately to their mining ventures. This 2000-word guide covers every nuance of the notification, including pay matrix details, eligibility breakdown, examination syllabus, and expert tips for cracking the PSU selection process.

- Mine Surveyor (S-2):
- Education: Full-time Diploma in Mine Surveying, Mining Engineering, or Civil Engineering with at least 60% marks.
- Certificate: Valid Mine Surveyor's Certificate of Competency (Coal) issued by DGMS.
- Experience: Minimum 04 years of post-qualification experience in mine surveying, preferably in open-cast coal mines.
- Mine Junior Overman (S-2):
- Education: Full-time Diploma in Mining Engineering with at least 60% marks.
- Certificate: Valid Overman Certificate of Competency (Coal) issued by DGMS, along with valid First Aid and Gas Testing certificates.

Selection Process and Examination Pattern
The selection process is meritocratic and relies on a Computer Based Test (CBT). There is no interview for these supervisory roles, ensuring that the final selection is determined by technical and general aptitude scores.
- Computer Based Test (CBT): A two-hour online exam consisting of multiple-choice questions (MCQs).
- Document Verification (DV): Candidates shortlisted in the CBT will be called for verification of their original DGMS certificates and experience letters.
- Medical Examination: Since mining requires high physical fitness and specific vision standards, selected candidates must clear the medical exam as per THDC standards.
Qualifying Criteria: To be considered for the merit list, UR/OBC/EWS candidates must score at least 50% in the CBT, while SC/ST/PwBD candidates need at least 40%.
Detailed Exam Syllabus
The CBT is divided into two distinct parts. Mastering both sections is essential to secure a rank in the merit list. The exam is typically available in both Hindi and English.
Part 1: Technical Knowledge (80% Weightage): This section is specific to the discipline. For Mine Surveyors, it covers survey instruments (Total Station, Theodolite, GPS), leveling, contouring, and Coal Mines Regulations (CMR) 2017 related to survey duties. For Overmen, it focuses on mining methods, strata control, explosives and blasting, ventilation, and CMR 2017 safety chapters.
Part 2: General Aptitude (20% Weightage): This section tests your mental agility and includes:
- General English (Grammar and Sentence correction).
- Reasoning Ability (Puzzles and Logic).
- General Awareness (Current Affairs and basic General Science).
- Quantitative Aptitude (Mathematics up to 10th Standard).
Preparation Strategy for THDC Mining Exam
Cracking a PSU exam in the mining sector requires a deep dive into the Coal Mines Regulations (CMR) 2017. Most technical questions revolve around statutory requirements and safety norms.
Technical Mastery: Mine Surveyors should practice numerical problems related to traversing and volume calculation. Overmen should focus on the duties and responsibilities mentioned under the CMR. Since you already have 4 years of experience, relate your field knowledge to the theoretical concepts in your textbooks.
Non-Technical Balance: Don't ignore the 20% general aptitude section. In many PSU exams, candidates with excellent technical scores fail to make the cut because they neglect reasoning or current affairs. Dedicate at least one hour daily to solving aptitude problems from standard competitive books.
Previous Year Papers: While THDC specific mining papers might be rare, you can practice with papers from Coal India Limited (CIL) or NLC India for Overman and Surveyor roles, as the technical difficulty level is comparable.

Frequently Asked Questions
- Q1: Can candidates with a degree in Civil Engineering apply for Mine Surveyor?
Yes, candidates with a Diploma or Degree in Civil Engineering can apply for the Mine Surveyor post, provided they possess the mandatory Mine Surveyor's Certificate of Competency (Coal) issued by the DGMS. Without this certificate, the engineering degree alone is not sufficient.
- Q2: What is the "S-2" Grade in THDCIL?
S-2 is a supervisory grade in the PSU hierarchy. It is higher than the S-1 entry-level grade. It provides a better pay scale and higher responsibilities, which is why THDC requires at least four years of prior experience for this grade.
- Q3: Is the 4-year experience mandatory?
Yes. The notification explicitly mentions that candidates must have a minimum of 04 years of post-qualification experience as on July 1, 2025. Experience gained before obtaining the diploma will not be counted.
- Q4: What are the qualifying marks for the CBT?
For General, EWS, and OBC candidates, the qualifying mark is 50%. For SC, ST, and PwBD candidates, the qualifying mark is 40%. Scoring below this will disqualify you regardless of the vacancies available.
- Q5: Can I apply for both posts?
Usually, the exam for both posts is conducted at the same time or in different shifts on the same day. However, since both roles require different DGMS certificates, a candidate can only apply if they have the specific certificate for that post.
- Q6: What is the age relaxation for OBC candidates?
OBC (Non-Creamy Layer) candidates are eligible for a 3-year relaxation in the upper age limit. This means the maximum age for them is 33 years as of the cut-off date. This relaxation is only for the reserved seats or as per government directives.
