| 摘 要： | 兖矿集团巨野煤田赵楼煤矿首采1302工作面在2009年5月底发生了一次突水事故,最大涌水量为290m3/h,造成工作面停产5d、处理被压实支架39d的后果。在分析井田地质及水文地质条件的基础上,通过现场水质化验以及观测孔水位等资料的研究,认为该工作面涌水水源为3煤顶板砂岩水,涌水通道为采动裂隙。并提出要采取查清水文地质条件、采前疏放、匀速推进、健全排放水系统等确保安全开采的防治水措施。

| Abstract: | A water bursting has happened in the No.1302 working face,first mining area,Zhaolou coalmine of Yankuang Group,Juye coalfield,in the end of May,2009.The maximum water inflow is 290m3/h and caused consequences of 5 days production suspending,39 days compacted supports processing.Based on minefield geological,hydrogeological condition analyses,combined with site water quality testing and observation borehole water level study,have considered that working face water inflow source is from No.3 coal roof sandstone,inflow channel is mining fractures.Finally put forward water control measures of to make a thorough investigation of hydrogeological condition,advance water drainage,even pace advancing,perfecting water drainage system to ensure safety mining. |
