摘要
对济北矿区葛亭矿下组煤不同底板岩层岩样的渗透性进行了试验研究,得出了各岩样的渗透性试验数值曲线,为进一步研究济北矿区各矿井深部底板承压水灾害预防控制关键技术提供了理论支持。
In Jibei Coal Mining Area,thick Ordovician limestone exists and a vast area of it is exposed,which constitutes greater threat to the extraction of the lower group of coal seams.Test study was conducted on the permeability of different floor rock samplers of the lower group of seams in Geting Mine of Jibei Mining Area,and the numerical curves of the permeability tests of each rock sampler were obtained,which can provide a theoretical support for further studying the key prevention and control technique for pressure water hazard in deep floor rock in each mine of this mining area.
