Hello, I'm currently studying mining and minerals engineering at VT(Switching to it next semester, so excited.) I'm taking diff eq right now and deforms next semester. I can't wait for explosives and fragmentation class. Any tips? I think this summer I need to review gen chem, statics and I am taking calc 3.

They are using high explosives. The gasses generated by the reaction are not important. In warhead design we discard the explosive and products as soon as the reaction is complete. By then the shockwave has entered the material and that is what does the work. If you used gunpowder then the pressure would be important, because that's deflagration. In HE the reaction is supersonic in the material, and that wavefront carries the energy.
As a shotfirer I can tell you the gasses are very important, the primers job is to heat up and initiate the explosive column, ea kg of loaded product will make 1000lt of gas's and the immediate expansion in the designed pattern is what throws all the rock or burden in the desired direction.

I am learning about underground hardrock mining prior to getting a job... this is a great video, thankyou!
Great video! As an experienced mine engineer I can say the video gives a true demonstration of the mining process... Only if there were more videos..
Thank you for your feedback. Perhaps this is something we can look into for the future :)

This was very interesting.
I'm very proud of you mountaintop removal coming to Southern West Virginia blast and all the mountains out
Very succinct and on point. Nice video.
Great video. Thankyou for sharing
Exactly what my woman will really appreciate as she studies Explosive Engineering at Ms.State University
Mo. State University
Me and my woman can learn this someday when I can afford my own property and a blasting permit.
Спасибо за видео. 😊
Very informative video, thank you
wonderful video to know about mining
I want to know about invert drilling process in metal mines
I am very excited to your video
I am blasting in mines area

Australian Centre for Geomechanics price?
Still an excellent video, even three years after first seeing it. :P
Hi JO,
Thanks for your feedback! We're pleased to hear that you enjoyed the video.

I inveted the system for using bulk explosives underground 😊
Nice info🤩🤩
fantastic video help me so much translate theory into act!
Hi Giwrgos,
Glad to hear that the video provided you with some useful information!

Something you dont get to do in civilian life. I'd for sure do this job

The problem I found on underground mines is that they never bother to tell the contractors when they are doing to blast
Usually at end ea shift, but all blast times should be posted where you can see on entry
We need more bridges interstates and highways in West Virginia
Hello, which blasting machine is safe, stable, best suitable for underground ?
Nice video explaining drill and blast! We got more videos on our channel here if you want to learn more about mining!

The amount of gas an explosive produces is of prime importance as well as the VOD
I don't know, but in the video, no efforts are mentioned to plug the holes.
Amount of gas is important
As a shotfirer I can tell you the gasses are very important, the primers job is to heat up and initiate the explosive column, ea kg of loaded product will make 1000lt of gas's and the immediate expansion in the designed pattern is what throws all the rock or burden in the desired direction.
Warheads and blasting ground are different things mate
