longwall mining was limited by the type of coal to be cut. With , this is no longer the case. Advancements in drive, control and transmission systems – with more powerful motors, stronger plow chains, increased plow speeds, higher advancing force provided by the roof supports, precise control of the cutting depth, and plow
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Coal mining - Coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
I would like to build a coal mine for my layout. However, I have no knowledge of coal mine operations. I don't feel the need to have every detail just right, but would like to have a general idea of what needs to be represented for a small mining operation pre-1950 time frame.
