WEST PITTSTON — The West Pittston Historical Society (WPHS) will present “Slopes, Shafts and Planes — the Mechanics of Mining” as a part of observing January Anthracite Heritage Month at the Trinity Episcopal Church, 337 Spring St., at 6:30 p.m. Friday, Jan. 30.

Mining engineer Justin Emershaw of the Hazleton-based Atlantic Carbon Group will be the presenter for the evening. This is Emershaw’s second presentation to the WPHS.

The program will include how and why mine shafts and planes were located, and how surveyors directed miners to where the tunnels and shafts are in the mine — all used for mapping the mine.

The program will also show how engineers find coal for a viable mine operation. The techniques cover both historic and modern-day mines.

The program is free and open to the public, with a handicapped accessible elevator available.
