摘要
根据煤巷围岩力学参数中有许多随机变量的特征 ,笔者应用工程结构可靠性理论 ,提出并建立了煤巷锚杆支护结构可靠性分析模型 ,得到了其可靠度的计算公式 ,提出了提高支护结构可靠度的措施 ,为优化煤巷锚杆支护参数提供了一种新方法。这些研究成果对指导煤巷支护设计 ,减少支护失效事故 ,保证矿井正常安全生产具有重要的意义。
Based on features of random variables in mechanic parameters of surrounding rocks of coal roadway,a model for reliability analysis on bolt support structure is established by applying the engineering structure reliability theory, from which the calculation formula is obtained. Measures to enhance the reliability of support structure are presented. A new method for optimizing the bolt support parameters of coal roadway is provided. The model could direct the support design,decrease accident of support failure,and would be significant in assuring mining safety.
