摘　　要：针对开滦赵各庄矿 13水平 (- 110 0m)F8断层破碎带穿越的首采区的安全回采评价问题 ,通过现场地应力实测、室内不同含水量情况下的断裂带物质的单轴、三轴常规和流变力学试验以及反演所确定的力学参数 ,对其进行弹塑性三维可视化数值仿真模拟 ,深刻地阐述了其弱化机理和主要控制因素 ,提出了煤层底板断裂构造突水时间弱化效应的新概念 ,并对不同水压、不同时效阶段条件下赵各庄矿 13水平首采区的安全回采方案作出了预测评价 .In the light of safe mining evaluations for the first mining district which is cut by fault F 8 in the thirteenth mining level in Zhaogezhuang Coal Mine, Kailuan, this paper adopts such methodology as measured ground stress, traditional and special rheological rock mechanics experiments, and three dimensional visual numeric modeling using FLAC 3D and discusses deeply their weak effect mechanisms for fanlt F 8, controlling factors, and presents a new concept of the time weak effect of fault materials under coal bed. The concept develops and enriches basic theory of water bursting in coal mine. In the last, different safe mining schemes for the first mining district at the thirteenth level in Zhaogezhuang Mine have been predicted and evaluated.
