摘　　要： 针对煤层注水难易性评价指标和权重为区间灰数的决策问题,提出基于核-灰度区间灰数的煤层注水难易性评价方法。该方法首先确定影响煤层注水难易性的7项指标因素,然后利用投影法确定煤层注水难易性评价指标属性的核权重和灰度权重,最后通过区间灰数相对核的排序方法对煤层注水难易性进行排序。 The attribute values and the attribute weights of coal seam water injection are interval grey numbers. The evaluation method of coal seam water injection difficulty based on the kernel-gray interval grey numbers is proposed. The 7 index factors which affect the difficulty of coal seam water injection are determined. Then the kernel weights and the grey weights of the index attribute of coal seam water injection are determined. An ordering method based on the relative kernel of the standard grey numbers is proposed.
