| 摘 要： | 以软岩层矿井复杂地质构造区域巷道掘进与围岩控制为工程背景,在对巷道围岩应力环境、岩体强度、围岩内部裂隙发育状况详细测定和围岩可锚性试验的基础上,提出"强力锚杆初始支护+破碎围岩注浆加固+高预应力锚索加强支护"的巷道围岩控制技术。实践表明,强力锚杆支护系统与破碎围岩注浆加固相结合的围岩控制方式,是解决复杂地质构造区域软岩层巷道围岩控制难题的有效途径。

| Abstract: | By taking roadway excavation and surroundings control in soft rock strata with complex geological structure as engineering background,a roadway surroundings control method was determined based on systematic geo-mechanical tests, including geo-stress environment, rock mass strength, joint fracture distribution, rock surroundings anchoring performance and so on. Then the surroundings rock controlling method combined with high-strength bolts initial support, broken surroundings reinforcement by grouting, supplement support with high pre-stress anchor cable was applied. It was proved that the method could make roadway surroundings in stable state by engineering practice and solve surroundings control problems in soft rock roadway with complex geological conditions. |
