- The operators view from inside a 2005 Hitachi EX1200-5 w/ 9yd bucket digging down to a mine fire and loading a fleet of Terex 33-11B mining trucks. Think mining's cool? Then join the PA Channel today!

What causes the mine fire to start? Blasting? Earthworms careless with their cigarettes?
There are a few ways an underground coal mine fire can start. Some soft coals will ignite from blasting. Anthracite is much harder to ignite and the most common way this coal ignites is at the outcrop as a result of people dumping garbage in old stripping pits.
Awesome video. Best excavator manufacturer on the market. Although there will be 20 people disagreeing with me on here.
Tax me I'm Canadian agreed and cats up there to.
Great video... I have been missing seeing your videos, you don't seem to put them up as much nowadays. always look forward to seeing them. take care.
I know, I had to cut back on how often I upload to rebuild by video reserve count.
Enjoyed your video Justin it has been awhile, have missed your videos.
Great video ! The driver looks like Todd Hoffman :-)
Hahaha!! I never thought that, but now that you mention it, your right!
Couldn't be Todd Hoffman , if it were the excavator would be broken , the ground would never be properly de-watered , the haul truck would be on it's side and the mine fire would have spread to the surrounding forest and that's just before lunch
How dose the fire start?🚜👍
Sehr schöne Video aufnahmen TOP .
Gruß Kalle
Great video!
Only one negative thing on this video...not long enough!!!
And I thought I did make it long enough lol. I could have made it longer!
I had the privilege to operate the first hitachi 1100 in Western Australia back in the nineties. Loved it. Very nice to operate. But still hard to bet a Komatsu pc1000 for shear grunt and strength.
NICE. I enjoyed watch'n this video of the New style hydraulic loader's. They wasn't even an thought back when I was work'n Construction job's, back in the day's of 0l'. he-he
I was always told never water a coal fire, even underground. Itl just flash steam before it even gets close to the coal, we put them out usually with lump coal, just pile up faster then it can burn.
digity digity do
I've actually seen them use those in minds around here they use it for some of the smaller jobs to move some of the smaller granite pieces to the crushers
Wow, that Hitachi has got some Balls! Its really quiet as well. Another great video PA. Thanks
when he diggs what is the white smoke is it fog the warm dirt hitting the cold air
Another great vid, PAmining. Love your work- looks like it was a cold day then! Keep up the great work.
I have a few requests for you if you're interested I would like you to do a documentary on the cat 320 D excavator and that caterpillar D11 T bulldozer
While there is a possibility I may film a new 11T, I will not film a 320D, sorry. I am a mining guy and this channel is strictly about mining-class equipment
the biggest escavator i have operate was a hitachi 355 EX.very good machine.now is that true ...the bigger they are its more easy and fun to operate?
Slower
Is that steam coming from the ground? If it is why is it steaming? Thanks for the vid. I always enjoy them.
That is actually steam from an underground mine fire. Plus the material he is digging is hot and dry from the fire, adding to more dust
Same -5 as in the walkaround?
great video could you do duc on a 797 please
Heavy shit!!
Great. Thanks for the ride.
is that dust or steam coming off the the rocks?
Both. Steam from an underground mine fire that his mining through, and dust from hot and dry the material is from the heat of the fire
Why was this not done 40 years ago in Centralia??
They actually tried to exhume the fire at Centralia years ago but failed. By the time a trench was dug to surround the fire it had already spread beyond it.
Good vid pard nice work!
So what happens after he gets down to the mine fire?
He'll mine right through it. There's only two ways to put out a coal mine fire- pump lots of water down boreholes or dig it out
r they cleaning up Centralia finally lol
Is the dirt naturally that warn, or is heat from Blasting? Lots of Steam .

PAmining Is this the Mine Fire that started in the 50's or so ?
VideosByAl Yes. It's been burning for decades. Now the plan is to develop a job and mine through the fire and take out the coal.
PAmining If you feel inclined, a Documentary on the Coal Mine Fire would be very interesting.
VideosByAl Sure will do. Seems to be an interesting topic for many
Nice. What are the handles in front of the driver, in the front window?
Those levers connect to the foot pedals on the floor and control the machine's travel. The whole reason those levers are there is for operator preference, to either use the foot pedals to travel the machine, or the hand levers.
PAmining I find personally for tracking forward 99.9% of the time I'll use my feet and tracking backwards it's about 50/50 depending on how fast I need to track. But it's waaay more comfortable to track with your feet so you can keep your hands on the sticks.
Is the smoke from the explosives used to breakup the rock face?
No the smoke is from the burning coal below the rock. You may also be seeing the steam from the heat generated from the burning coal.
Hello,
Why is coal burning underground?Combustion needs oxygen where is it coming from?
Peprita Heart There are a few ways an underground coal mine fire can start. Some soft coals will ignite from blasting. Anthracite is much harder to ignite and the most common way this coal ignites is at the outcrop as a result of people dumping and burning garbage in old stripping pits. The oxygen the fire receives is from all the old underground workings, slopes, air shafts, etc.
Really cool!
what happens to the burning overburden once removed ?
+allan egleston The overburden gets hauled to the backfill site where it is used to fill in the old pit once the coal has been extracted
Is this in centralia?
No. Centralia is not the only mine fire in Pennsylvania.
Nice video.. but once down to the fire ,is it just smouldering ? & how much of the coal is still good or viable
Coal fires move slowly and there is still millions of tons of good coal on the property. It is not a rapid burning, more like a smoldering. Even so, core temperatures are so hot on this job that blasting has to be done in small sections because the heat of the fire was essentially burning up the ammonium nitrate.
how you guy's still working can't get a mining job in eastern kentucky cause the mining has been killed
+Christopher Robinson Different type of coal up here. This is a high-carbon coal used for water filtration, glass manufacturing, and steel production. Not your typical steam coal. Either which way, we need Trump in office to bring back coal!!
