摘　　要：针对赵庄煤业运输顺槽过超高冒落区问题,根据冒落区形态制定了“底部冒落碎矸注浆+顶部空洞充填”治理方案,并制定掘进期间二次浅孔注浆和锚索补强支护方案。实施结果表明:掘进期间固结体粘接良好,8 d安全通过12 m冒落区,掘进后巷道变形量极小,15 d后基本不再变化。In view of the problem that Zhaozhuang Coal Industry's transportation gateway passes through the ultra-high caving area,according to the shape of the caving area,the treatment scheme of"bottom caving broken gangue grouting+top cavity filling"is formulated,and the secondary shallow hole grouting and anchor cable reinforcement support scheme during the excavation period are formulated.The implementation results show that:during the driving period,the consolidation body is well bonded,passing through the 12 m caving area safely in 8 days,the roadway deformation is very small after driving,and it basically does not change after 15 days.
