探讨了高水平应力软岩巷道的破坏机理,提出解决高水平应力软岩条件下巷道支护的技术途径,采用锚网梁+锚索+卸压的巷道综合支护技术方案,并通过对某矿区1201运输顺槽工业性试验证明,此种支护形式是经济、有效、实用的高水平应力软岩巷道支护方式。
This paper discusses the failure mechanism of soft rock roadway with high horizontal stress and puts forward the technical solution to the roadway support in soft rock with high horizontal stress. The technical scheme of roadway comprehensive support with anchor beam + anchor + pressure relief is adopted, Industrial tests of the transport area 1201 in the mining area have proved that this kind of support form is an economical, effective and practical high level stress soft rock roadway support mode.
