Methane Content News Today

If we have something below that, it could be one of two things. there could be a small leak or there could also be a condition where youve had some depletion of the reservoir. when you draw the fluid -- in your example that you gave in letting air out of a tire, if you let some air out of a tire and you stop, the pressure is going to be lower. thats what youre seeing. unlike the tire, in a reservoir, oil and gas can fill in from the outer reaches of that reservoir and start to build that pressur...

When you have an explosion in your experience of this strength, of this depth, would there not have been a methane sense or some gas sensor that should have given them if only for a second some warning? >> well, you can install what we call minewide monitoring systems and these systems can be located throughout the mine and give you continuous readouts on methane content, carbon monoxide content, et cetera. i do not know if that mine had that. i suspect it probably did not. and that the gas rati...

Methane as well as carbon monoxide, the methane is explosive. from about 5 to 15%, so once the air with the methane content got above 5%, it was too dangerous for the teams to work in there. just a spark could cause another explosion. >> given the fact they think its a long shot to find these four miners alive and theyre not willing to risk the lives of the rescue crew to get in there. thank you. >> youre welcome. the u.s. military has confirmed the latest hostage video released by the taliban...

Feet of air delivered to various places in the mine. the gas levels have to be down below -- the methane content has to be down below 1%. so my question is if he was getting this many citations, the ventilation system was not delivering that amount of air to those places and i would question if the ventilation system was capable of actually doing what the operator said it was doing and mshas citations could validate that question. >> i have a list in my hand of all the citations just this year a...

And its -- theyre very understanding. bruce dial has investigating several mine fatalities. lets go back to this morning when they said, we have to get these crews out of there. so close. just about 1,000 feet away from a rescue chamber. put that into perspective for us. >> what they did after they drilled the hole frs the surface down to help ventilate the area, they sent the crews back in. well, these holes that theyre putting down would only allow about 850 cubic feet of air into the that are...
