摘要
阐述了长锚索补强支护某铁矿松软破碎矿体中回采进路的方案及参数设计过程以及现场施工情况,并简要介绍了锚索支护结构的受力分析、效果观测等工作,给出了所取得的主要结果。实践证明,所确定的支护方案及参数是有效的,进路回采中支护结构安全可靠。
This paper describes the scheme and parameter design, construction on the spot, mechanicalanalysis and mornitoring of the cable bolt support system for the stoping drifts in loose and broken ore bodies.Some conclusions are drawn. The test results showed that the scheme and parameters used are valid and thesupport structure is safe in stoping.
