摘要:
为了研究组合串联煤岩对冲击倾向性的影响,采用RFPA数值模拟的方法,对顶板-煤-底板组合煤岩进行数值试验研究,通过改变顶板刚度和煤岩(顶板)高度比参数进行模拟,分析不同煤岩组合模式对冲击倾向性的影响。试验结果表明:随着顶板刚度的减小,组合系统的冲击倾向性随之增强; 随着煤岩高度比的减小(顶板厚度增加),组合系统的冲击倾向性也越来越大; 串联煤岩组合系统冲击倾向性与顶板刚度、煤岩高度比呈反比关系。以上试验结果为揭示煤岩冲击倾向性提供了理论依据及工程参考。
Abstract:
In order to study the influence of rockburst tendency by the combined and integrated coal-rock,by using RFPA numerical simulation method,experimental research was carried out on the roof-coal-floor value of integrated coal rock,the influence of different combination modes between coal and rock on its bursting potential was studied using numerical simulation by changing the stiffness of roof rock and height scale.The experimental results showed that:the bursting potential improves with the decrease of the roof stiffness and the height scale(increase thickness of roof rock),the rockburst tendency of combined and integrated coal-rock is inverse relationship to the stiffness of roof and height of coal-rock.These results provide a theoretical basis and reference for engineering to reveal the rockburst tendency of coal-rock.
