摘要
通过理论分析和试验研究,建立了巷道围岩裂隙系数与巷道轮廓位移量之间的相关关系。介绍了采用注浆锚杆兼作注浆滞后时间指示锚杆的方法和原理,分析了开始注浆时巷道围岩裂隙系数的合理取值范围,给出了确定巷道轮廓位移量的诺模图.
Based on the theoretical analysis and testing studies,the relationship between the fracture coefficients of surrounding rocks and the peripheral displacements of the laneway is set up.The theory and method of the grouting bolt are also put forward,which can be used as a instrument of lagged time for directing grouting. Furthermore,the reasonable range of fracture coefficient of surrounding rocks at the beginning of grouting is examined,and the nomogram of the displacement of laneway profile is determined.
