陈四楼矿迎采动沿空掘巷技术研究及应用

 摘 要：针对陈四楼矿2409轨道顺槽迎采动沿空掘巷工程中，小煤柱破碎，巷道围岩矿压显现剧烈问题，通过迎采动沿空掘巷围岩稳定性分析，认为特殊的时间安排和空间位置是迎采动沿空掘巷难题的关键，提出强化顶板、强化煤柱、强化初期支护的技术思想；以2409轨道顺槽迎采动沿空掘巷为工程背景，设计相应支护参数，巷道采用高强锚杆、M型钢带、金属网及锚索梁联合支护，工程实践表明巷道维护效果良好。

Research and Application of Gateway Driving Along Goaf forward to Adjacent Mining Coal Mining Face in Chensilou Mine

According to the broken small coal pillars and serious mine pressure behaviors of the gateway surrounding rock occurred in the gateway driving along the goaf forward to the adjacent coal mining face in No.2409 railway transportation gateway of Chensilou Mine,with the analysis on the surrounding rock stability of the gateway driving along the goaf,the paper held that the special time arrangement and space location would be the key difficulties of the gateway driving along the goaf.A technical idea with the initial reinforced support was provided to the roof and coal pillar.Taking No.2409 railway transportation gateway driving along the goaf forward to the adjacent mining as the project background,the relative support parameters were designed and the high powerful bolt,M type steel band,steel mesh and anchor beam combined support system was applied to the mine gateway.The project practices showed that the maintenance effect of the gateway was excellent.
