| 摘 要： | 根据现场调查、勘探成果,在煤田地质环境条件分析的基础上,简要阐述受煤田开采工程活动综合影响下的抚顺城区地裂缝基本发育特征及成因。抚顺城区地裂缝是受采矿及F1、F1A等断层带等因素综合作用,地表岩土体开裂,在地面形成一定长度和宽度的裂缝,通常随地面变形、地面沉陷的发生而发展,是采空区上部地质体结构发生变化的外在表现,当断层发生局部活化效应时,对地裂缝起着扩散放大作用,为此提出相应的防治对策。

| Abstract: | Based on the field investigation,exploration results,and analysis on the geological conditions,this paper presents the basic developmental characteristics and causes of ground fissures in Fushan city under the combined effects of coal mining engineering activities.The study shows that the ground fissures are caused by the combined impacts from mining activities and F1,F1A faults.The fissures of rock mass and soil body form a certain length and width of cracks at the ground surface.The cracks are developing ... |
