依据恒源煤矿勘探阶段和生产过程中的地质资料,对恒源煤矿6煤底板岩层岩性特征分析评价,划分出底板岩体岩性类型;在统计分析平面变形系数和断裂分维值的基础上采用灰色模糊评价法划分6煤底板岩体结构类型,综合底板岩性-结构类型将底板岩体稳定性分为4类,为该矿底板防治水工作提供基础资料和科学依据。
Based on the geological data of exploration stage and production process of Hengyuan Coal Mine, the rock lithology characteristics of 6 coal seam floor in Hengyuan Coal Mine are analyzed and evaluated to classify the lithology types of the base rock mass. Based on statistical analysis of the basis of the deformation coefficient and fracture fractal dimension On the basis of the gray fuzzy evaluation method, the structure type of the 6 coal floor rock mass is divided and the stability of the floor rock mass is classified into 4 types by comprehensive lithology-structure type of the floor plate, which provides the basic data and scientific basis for the water prevention and control work of this mine floor.
