煤矿顶板稳定性分析研究

摘要
煤矿顶板的稳定性一直是人们关注的问题。通过现场监测和试验获取了影响顶板稳定性的4个参数的分布规律,并分别应用极限平衡法和概率矩点估计法对青龙寺煤矿5-20102回风巷道顶板的稳定性进行了分析计算。结果表明:极限平衡分析法和概率矩点估计法的计算结果基本一致,5-20102回风巷道顶板处于整体稳定状态,但概率矩点估计法给出了顶板失稳的概率P_f=0.015 3,预示顶板局部失稳的可能性存在,较好地弥补了极限平衡分析法的不足。
The stability of the coal mine roof has been the concern of the people. In this article,we through field monitoring and testing to obtain the distribution rule of four parameters which influence the stability of roof,and the 5-20102 return air roadway of Qinglongsi Coal Mine roof stability has carried on the analysis and calculation with the limit equilibrium method and probability moment point estimation method. Results show that the limit equilibrium analysis method and probability moment point estimate method of the calculation results are basically identical. 5-20102 return air roadway roof in overall stable state. But probability moment point estimation method gives the roof instability probability P_f= 0. 015 3,it indicates the possibility of a top plate local buckling,better makes up for the deficiency of the limit equilibrium analysis method.
