My name is Kumar Rahul. I passed my Diploma in mining engineering in year 2018 from Jharkhand Rai University located at Kamre, Ranchi. My family belongs to mining background and thus pursuing a career in mining has always remain a dream for me. Having a decent education of mining from JRU Ranchi, I applied in gas testing examination in year 2019 and passed the examination in my first attempt.

Having all these, I did my online payment of Rs. 300 for gas testing examination through Bharatkosh ( and took the print out of the receipt of Application fees paid.

Then I downloaded the latest valid prescribed gas testing application from website of DGMS. I carefully filled every details asked in the form with ball blue pen. I affixed a duly attested passport size (3.5 cm x 3.5 cm) photograph with my name clearly written on the front top side of photograph.

A self-addressed envelope of A-4 size was also required. Copy of Aadhaar card was required too.

Also, I made an affidavit in the prescribed format which mentioned that “all the documents and certificates submitted along with the application and the information provided in the application are GENUINE”

I made a check list of following documents that were asked to put as enclosure along with the filled gas testing application form:

His experience at examination centre

 My examination centre was at VTC West Bokaro, Ghato dated 18-06-2019. I was much worried for my exam as that was my first attempt without any experience of the environment of any such oral examination of its kind. To have a good impression I had dressed up me formally along with short hair too om my head. I had a proper decent look. When I entered the centre after inspecting me admit card, I was called to set in a room. Then an instructor came in with a bag which contained the submitted documents by post of all us applicants. After verifying the documents, the instructor said us to go to a room for the oral exam. That room was for first examiner. I politely asked to enter the room. My examiners were a manger and a Project officer in that room. Firstly, the manager asked about me a simple introduction. I was feeling nervous during that conversation, though I answered well. But some nervousness kept reflecting out of my body. He in a friendly way told me to calm down and don’t to fear. Then some questions were asked both by the manager and project officer. I answered all up to my preparation and knowledge. Then they asked to enter a dark room basically the gas testing chamber, which I have heard before but never visited such a room before. I entered the room with manager. He told me to see carefully each flame safety lamp placed, he asked me about the percentage level of methane in the lamps there then we came out the room. He then boosted my confidence and said me to go to the second room. The second room was for an examiner from DGMS/DDMS or a Mining Inspector.  I asked politely again to enter the second room. This time was confidence level was better. The DDMS officer sited there asked my formal introduction and then asked about the different instruments placed there on table in the room. He said me “I am very happy to see you as you are a diploma holder from a newly established private mining university but even your knowledge part and recall of field experience is better than many”. I felt glad enough. I said “Thank You sir”. He wished me best of luck and allowed me to exit the room and wait outside for the results. I came out and I was quite excited for my results.

After completion of everyone’s examination it took two hours to come out of the results.

The results came on a printed paper attached to the bulletin board in the campus boundary. The crowd of applicants gathered in minutes to check their names in the list. I was also quite excited and praying to god at the same time. I checked the list and found my name as well as my father’s name printed there, a goose bump came out of my body and a little bit tear but all those were of happiness.
