| 摘 要： | 为了解决采深不断加大的软岩巷道掘进迎头片帮安全问题,运用岩体力学、材料力学、地质学理论方法研究了软岩巷道掘进迎头片帮机理和巷道掘进迎面墙锚杆布置优化方案。结果表明:圆形软岩巷道掘进迎头片帮部位随其断面垂向尺寸的渐变而变化,其垂向尺寸最大的条带区是最需加固的部位。该成果对现场掘进迎头的片帮防治具有一定的参考价值和指导意义。

| Abstract: | In order to resolve the safty problem of windward wall spaUing off in deeper and deeper shaft driving soft rock roadway,the theory methods about mechanics of rock mass and materials mechanics and geologic mechanics are used to study its mechanism of spalling off and its optimial rockbolt arrangement scheme.The result indicates the position of spalling off windward wall changes with vertica direction size on it,and the highest twig region is the position needing to be fasten,the achievement has a reference value and guidance significance for preventive treatment of windward wall spalling off. |
