Why Were So Many of the Mines Slope Mines Rather Than Drift Mines?

Why were so many of the mines slope mines rather than drift mines?

Okay, why were so many of the mines slope mines rather than drift mines. I think SR&W is one of the few drift mines. Anyone have any good technical information on mining? Why slope vs. drift? Where did they get the rail, which is smaller than railroad rail? The breakers used plates with various sizes of holes to sift the coal. I suspect those shaker plates come from abandoned breakers. The Wandering Woodsman. Anyone know anything about him and how to contact him? He had two videos on the north side of Short Mountain in Dauphin county and one of them showed slope mines where the entrance was covered with bars. Also, what looks like a ventilation shaft, not too old, as it wasn't rusted. Was that for mines on the south side of the mountain? I suspect all of the mines on the south side of the mountain are now abandoned. Near as I can tell, Darryl Koperna was working on the south side, and he would now be in his 60's, or older. The road on the north side looks like it was abandoned about fifty years ago, considering the size of the trees.

Slope, drift and shaft. It's about where the mineral is and how to get at it best.

I goggled "the wandering woodsman" & it lists different videos he has done.Is that what you wanted ? Or did you want to talk to him ? He is a personal acquaintance of mine.

I made the initial post about who the Wandering Woodsman was. He has some really nice videos, but I don't think he will be able to answer all of the questions I have.

What I would really like is to find a current, or retired miner in the Southern Field. Lykens area or Good Spring? Why slope mines vs. drift mines? Were these guys just going down into old slope mines and extending them. Very few drift mines. The mines went N-S, but the veins went E-W, so how did they determine when and how to blast another hole into rock to get to the next vein? We all know there had to be pillars, but how did they determine where to leave the pillars. How did they get the coal to the slope mine entrance? Must have been by rail. Where did they get the rail, which is smaller than railroad rail? Muckers? How did they get rid of the overburdon of rock to get to the next vein and get it out of the mine. Here in the southern field, I think the overburdon is Pottsville Conglomerate. not shale. That's hard rock. Ventiliation? All of this mining is either electric or air powered. How did they get the air lines down and blow out CO2 and methane? Bunch of technical questions that only a miner could answer.

Okay, any miners, retired or otherwise want to comment. This is all the technical stuff about anthracite mining and should not be lost. We've all seen the pictures of abandoned mines, so let's hear it from the guys who worked there.

Got me doing a little research. Drift mines would be the least costly above water. Slopes are more economical in most cases due to the pitch of the vein and depths. A slope might cost 5 thousand dollars per 100 yards in labor. A shaft would be 30 thousand per 100 yards. These are 1866 prices. The shaft would mainly be used in a shallow basin.

Bill, you didn't install a location to your profile. Like Fred said, there's a great offer, if you happen to be in Jacks neighborhood. Very generous of you Jack.
