A large Ordovician limestonelagged water bursting happened after 2006 No.

2006年曹窑东井27080工作面突然发生大型奥灰滞后突水,最大涌水量达到1 693m3/h,通过矿井水文地质条件分析,曹窑东井及相邻西部四矿大部分区域已处于"突水危险区"。

Based on the systematical collection of the hydrogeological data in the exploration stages and operative mines of the Yanzhou Mining Area,the hydrogeological characteristics of the Ordovician Limestone aquifer at the floor of the lower group of coal seams were analyzed,and water abundance of the Ordovician Limestone was districted to several subsections according to the unit water inflow rate.

在系统收集兖州矿区各勘探阶段及各生产矿井水文地质资料的基础上,对兖州矿区下组煤底板奥灰含水层的水文地质特征进行了分析。
