超化井田二1煤层厚度变化规律定量研究

QUANTITATIVE ANALYSIS ON THE THICKNESS VARIATION OF NO.2-1 COAL SEAM IN CHAOHUA MINE FIELD

摘要: 超化井田二1煤层空间展布具有分带性、定向性、等距性和岛列性等基本规律。趋势面分析揭示了井田尺度煤厚变化的主体特征;方向梯度和滑动窗口变异系数分析是对煤厚变异性定量描述的一种新参数。

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.
