to support the fill around the opening and keep it from collapsing on itself.

Question about gated mines.

Do all bat gates get locked with w/e type of lock or are some permanent? Is it because some mines have become totally unstable as to others that can still be explored? Does it come down to each individual as the decsion to it's location to the public or just an overall decision in general?

Some get locks... some are permanent. Theres one on a drift up by the mine fire that's permanent, and slope no. 179 got a permanent one, but then the one on the Pine Ridge No. 34 tunnel has a lock.... OSM makes that decision, and really..... I can't tell you why... Chris might have asked them about that once. don't know. Maybe they figure they might go back in someday for a bat study.

Did they take down the fan house and gate the opening that was inside of it yet?

Some Smaller mines that are sealed as part of the 126 acre archbald reclamation area. we were previously in before being sealed with tubes and gates.


Are these the ones up on the mountain behind the shooting range?

Is it safe to assume that Coaldale No8 is a sister mine to the No 9 tour mine?

On the reclamation project, what is the purpose of leaving the old workings ventilated, beyond bats?

I would think that if the area was remote enough, they would either surface mine and contour or blast the krap out of the shallow tunnels, get subsidence out of the way and move on.

Besides with the size of the tube, its only a mini-slope.

they mainly do it for the bats. however there are exemptions for gas. lehman no.179 slope was gated at both the main slope and fan house as well as a 30" borehole that was drilled down into it to ventilate the black damp out. if this mine was sealed blackdamp would seep into peoples basements that live above it. before the borehole was installed some land owners pilot lights would blow out in their furnaces! the no.1 fan at the lackawanna mine tour also uses this as an intake airway and sucks the blackdamp out there. as for the no.8 in coaldale, there were several in that area..... as you can guess with the 8 and 9. those 2 were mainly the largest but they all were connected in one way or another. there is a rock tunnel connecting the 8 and 9 on the 4th level i believe. mike a. would know for sure. however that is flooded below over 500 feet of water. and yes the no.8 is currently being strip mined out.

To answer the question, my guess is that the locked bat gates are probably created to allow access to the mine for the study of bats. At least in this area, there are many bat preservationists who conduct bat study of mines. And thus they need the ability to get beyond the bat gates. The NJ DEP does that and there are a number of other agencies in this area who run multiple studies a year. While there are a few coal mines with significant colonies (1000+) of bats, not all of them do. It probably has a lot to do with air quality and coal mines are not known for their air quality.

Chris, Why Plastic Pipe with the metal grating through it? I hope that is temporary.
