摘要:煤矿生产过程中,含水底鼓巷道治理是一大难题,新型耐水結固判的研发显得尤为
重要。选取本身强度高,水城环境内能稳定引发固化的改性聚酯为主体,研制成功耐水铺固剂。
并对耐水错固荆抗拔力、不同孔径含水管内緒国力、普通舗固剂与耐水锚固剂抗拔力対比进行
了试验研究。研究表明:时水错固剤水内緒固抗拔力达200kN以上;45mm管内索固カ
均在150kN以上;50m管内结索锚固力均在110kN以上;耐水锚固剂在100%积水率結管
内抗拔力平均值为196.3kN,优于普通固剂在积水率49%的锚固效果,高出2.86倍。新型耐
水結固剂工业性试验选取蒋家河渫矿二号采区回风大巷底鼓段,成功提高施工效率、编短工期,
减少了水对底板鏋索同力降低的影响。

1概述
巷道闭合和报废。巷道的破坏性底鼓有时还会产生冲击地
压,给矿工生命和生产设备造成威胁。我国是产煤大国,
在煤炭生产中,巷道、硐室经常会因进和采动等影煤炭产量居世界首位,煤层埋普遍较深,矿压较大,资
响使围岩承压过高而出现底鼓。强烈的底鼓会引起巷道断料显示大多数矿区不同程度地出现过巷道底鼓的现象。因
面变小,使巷道基础不稳,生产运输受阻,通风不畅,严此,对巷道底鼓的研究和治理一直是采矿业研究的重点
重影响矿井的安全生产,降低矿井生产效率,甚至会造成解决巷道底鼓尤其是软岩巷道底鼓一直是世界性的技术难
