Analysis on Mine Strata Pressure Law of High Cutting Coal Miming Face in Shallow Depth Seam Under Thin Base Rock and Suitability of Powered Support

No.326-01 high cutting fully mechanized coal mining face in Nayi Mine was a typical high cutting fully mechanized longwall coal mining face in a shallow depth seam.With a site observation study on the support resistances of the hydraulic powered support applied in the coal miming face,the paper mastered the mine strata pressure law of the high cutting fully mechanized coal miming face in shallow depth seam,analyzed the suitability of the powered support applied in the high cutting fully mechanized coal mining face and revealed the roof weighting features of the fully mechanized longwall mining face in a shallow depth seam.The study results could provide the references to the safety and high efficient mining of the high cutting fully mechanized coal mining face under the similar conditions.
