broken surrounding rocks gateway bolt support
基于济三煤矿围岩破碎条件,以163下02c胶带运输顺槽为例,分析了回采巷道低预应力锚网梯支护方式下,巷道支护效果差的内在因素。在原有支护方案的基础上,提出了高预应力锚网带支护方案。结果表明:巷道支护效果良好,锚杆支护实践取得进展。
基于濟三煤礦圍巖破碎條件,以163下02c膠帶運輸順槽為例,分析瞭迴採巷道低預應力錨網梯支護方式下,巷道支護效果差的內在因素。在原有支護方案的基礎上,提齣瞭高預應力錨網帶支護方案。結果錶明:巷道支護效果良好,錨桿支護實踐取得進展。
기우제삼매광위암파쇄조건,이163하02c효대운수순조위례,분석료회채항도저예응력묘망제지호방식하,항도지호효과차적내재인소。재원유지호방안적기출상,제출료고예응력묘망대지호방안。결과표명:항도지호효과량호,묘간지호실천취득진전。
Base on the geological conditions of the broken surrounding rocks in Jisan Mine,take 16302 tape gateroad for example,the paper discussed the inner factors of the poor gateway support results with low pre-stressed bolt,steel meshand ladder support method in the mining gateway.Base on the previous support plan,the paper provide the support plan with the high pre-stressen bolt,sheel mesh and steel strip.the results showed that the gateway support results were good and the bolt support practices were obtained with the progress.
