摘要: 以兴胜煤矿0913回风巷道掘进工程为背景,采用数值模拟的方法,分析了采动影响条件下窄煤柱沿空掘巷围岩控制技术,提出了科学的支护方案,有效控制了迎采工作面沿空掘巷围岩变形,缓解了矿井采掘接替紧张。0913工作面回风巷在迎采动工作面沿空掘巷条件下技术经济效益显著,不仅给兴胜煤矿以后类似条件下巷道掘进带来宝贵的经验,而且给周边矿井甚至全国类似条件煤矿迎采动沿空掘巷提供了难能可贵的技术参考。

Abstract: Based on the background of Xing Sheng coal mine 0913 wind tunnel excavating, using numerical simulation method, analyzed the effect under the condition of narrow coal pillar along gob roadway surrounding rock control technology in mining, put forward the scientific supporting scheme, control the attack mining goaf surrounding rock deformation along the working face effectively, alleviate the mining stress. 0913 working face return roadway in mining working face goaf roadway under the condition of significant technical and economic benefits, not only to the mine roadway under the condition of similar future brings valuable experience, and even the similar conditions to the surrounding mine coal face along goaf was to provide technical reference for valuable mining.
