【摘要】 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。更多还原

【Abstract】 Based on the exploration phase and geological data in the process of production in Hengyuan coal mine,the lithology characteristics of No.6 coal floor have been analyzed and evaluated as well as coal floor rock lithology types has been divided. Statistics and analysis of plane deformation coefficient and fracture fractal dimension values were used to divide No.6 coal floor rock mass structure type based on the grey and fuzzy evaluation method. Composite floor lithologic and structural classification of floor rock mass stability can be divided into four categories. Scientific basis for the prevention and control of the mine floor water is provided.更多还原
