| Abstract: | The zonation,orientation,equidistance and island arrangement are the fundational laws of distribution of No.2-1 coal seam in Chaohua mine field,Henan province.The trend analysis of coal thickness shows its distribution regularity on a whole mine field scale,whereas the orientational gradient and variation coefficient in a gliding window are the new parameters used to demonstrate quantitatively the thickness variation of coal seam. |

| Keywords: | thickness of coal seam change trend surface analgsis orientational gradient variation coefficient |
