Modeling Of Underground Coal Mining Processes …

Oct 07, 2019 Abstract. This paper presents a comprehensive simulation model of underground coal mining processes in a fully mechanized longwall mining face. A number of simulation experiments were performed. The face productivity is estimated as a function of various factors such as the technical parameters of mining machines, face length, gas factor, shearer operation mode, distributed geomechanical characteristics of coal seam.

If the coal seam is dipping, then an incline and winder might be used to get to the coal and to get the coal out of the mine. The time period and location can also have a significant effect on the how the prototype did it and what a model might look like and what the coal coming out of the mine looked like as well. In days of hand mining the size of coal was important and mining was designed to get the …
