Research on distribution regularities of small structures in Coal Seam 11-2,Panyi Coal Mine

With the tectonic geological methods the development properties,the forming mechanics of faults in Coal Seam 11-2 in Payi Coal Mine are analyzed.According to the distributing regularity of the small fault in the excavated area and the research of the stress field of the well structure,the structure distributing of the area that haven′t excavated is forecasted.It will be very significant to insure safety working in the mine,improve the economy benefit of the mine and the long term programming of the mine.
