Effects of Coal Mining Height and Width on Overburden Subsidence in Longwall Pier-Column Backfilling

Longwall pier-column backfilling is a partial backfilling technique initially designed in thin coal seam mines. With the increase of mining intensity, the mining height and width of the backfilling working face will also increase. It is necessary to analyze how changes in working face dimensions inf...
