Decision and analysis of buildings for protective coal pillar method in the western loess area
In order to protect the ground buildings and structures from damaging caused by underground mining, a certain mining area of the buildings is taken to reserve protection coal pillar design for the prototype and commonly select the vertical section method and perpendicular method studied under different mining depth, dip angle of coal seam and different trends relative to building owners of the coal amount of circumstances, and carries on the analysis comparison in actual production.The results provide the basis for the protection of the buildings on the ground, the rational development of coal resources and guidance under different conditions.By doing this, not only are the buildings protected from damaging, but also the recovery of coal resources increase in some degree.At the same time, it is very significance for the reserve protection coal pillar under the buildings in other mining area.
