摘要
根据计算所得煤层底板倾角变异系数R值,将未采区划分为4种构造复杂程度类别,从而找出未采区不同地段断裂构造的差异性,还可根据R值等值线的方向判定未采区主要断裂构造的走向。
In Furong Coal Mine, the unmined sections were divided into four categories of structure complexity on the basis of the calculated dip variation coefficient 'R' of the seam floor so as to find out the differences of faulting structure in various sections. Also, could be deducted the strike of the main faulting structures in unmined areas from the direction of R contours.
