Evaluation on coal mining conditions and fully mechanized mining suitability of Shogoucha coal field
This paper used a large of geological borehole of Sha Gou-cha Coal in Shenfu coalfield,Based on the analysis of the geological structure,coal-seam thickness and its regulations,roof and floor conditions in Shagou Cha Coal,then evaluated seven coal seams full mechanized adaptability,evaluation results show that:4-3,5-2coal seam could be full mechanized in an area of coal mine.The mine conform to the basic characteristics of the greater the thickness of coal seam is,the smaller the coefficient of variation is,the more suitable for fully mechanized is; the smaller the thickness of coal seam is,the greater the coefficient of variation is,the less suitable for fully mechanized is.
