摘　　要：通过对浑河断裂带(抚顺段)的地质调查、人工地震勘查、断裂绝对年龄测定、跨断裂形变测量等资料的综合分析与研究,讨论了断裂构造的近期活动特征,并据此认为浑河断裂自晚更新世以来若非人类工程活动扰动是没有活动的,现今的断裂活化效应是由于大量的人类采煤活动造成的。由于断裂的活化效应破坏了抚顺煤田及其周围区域原始构造应力场的平衡状态,为达到新的平衡必然导致应力的重新集中与释放,在此过程中伴随产生了抚顺煤田广泛发育的滑坡、地面沉陷、矿震、地裂缝等地质灾害。Through the geological investigation into Hunhe fault zone （Fushun section）, the artificial earthquake investiga- tion, isotopic dating of the fault, and survey of the fault deformation, the paper discussed the fault structure short-term activity characteristic and suggested the Hunhe fault not broked since Epipleistocene without the human activity perturbation. The nowadays break activation effect is caused by the massive humanities mine coal Because these breaking activaties destroyed the Fushun coal field and the peripheral region primitive structure stress equilibrium, achieving a new balance would had cause the Fushun coal field widespread landslide, the ground subsiding, and the mine shake.
