摘　　要：抚顺煤盆地是受浑河深断裂控制的新生代构造盆地.浑河断裂不仅对含煤建造的形成和演化具有重要的控制作用,而且对区域地壳稳定性、对西露天矿边坡和石油一厂的地面变形亦具有重要的影响。作者在现场调查的基础上,对浑河断裂带的F_1、F_(1A)的断层泥进行了宏观的综合研究.采用多种现代方法测定了断层泥的地质年令、颗粒和粘土矿物组成、微结构特征、物理化学和物理力学性质。据此,作者论述了断层泥对区域地壳活动性、对地下水的空间分布、对边坡和地面变形的影响.The Fushun coal basin is a Cenozoic structural basin controlled by the Hun River fault. This fault not only plays an important role in controlling the forma- tion and evolution of the coa-bearing series but also affects seriously regional crust stability, the slope stability of the west open pit and the surface deformation of Fushun Petroleum Refinery No. 1. Based upon the results of field survey,synthetic studies of gouges from the fault are made both maeroseopieally and microscopically. The geological age,grain size, clay mineral composition, mierostrueture, physicochemical and physicomechanical properties of the gouges are measured using a number of modern methods.with these results as a basis, the effects of gouges on regional crust activity, on the distribution of groundwater, on slope stability and on surface deformation are discussed.
