根据工程场地岩土体的破裂,以辽宁抚顺地裂缝为例,采用理论解析、数值模拟等手段,开展了矿震引发地裂缝扩展效应探讨.研究认为:煤田开采破坏了抚顺地区的地质环境,浑河断裂带是抚顺地区发育地裂缝的地质构造基础,采煤沉陷为地裂缝的发育提供了运移空间及应力条件,该地区频繁发生的矿震加剧了地裂缝的扩展及破坏作用.

Based on the point of rock fracture in project site, taking the earth fracture in Liaoning Fushun for example, the research on earth fracture expansion effect caused by mining tremors, with using method of theory analysis and mathematical imitation is launched. The study proves that coal field exploitation destroys the geological environment of Fushun. Fracture area of Hunhe is the geologic basis of earth fracture growth in Fushun. Mining subsidence provides movement space and stress condition for the growth of earth fracture. Frequent mining tremors aggravate the expansion of earth fracture and its damage function.
