邢东矿-980水平以深区域奥灰突水机理的研究

Study on Xing Dong Mine-980 levels in the deep area ash water inrush Mechanism

我国华北地区矿井主要受奥灰水的威胁,邢东矿地处华北地区,受其煤层赋存条件的影响,在进行采掘活动的同时,严重受奥灰高承压水的制约。为有效防治邢东矿奥灰突水,特对该矿2127工作面、2222工作面底板突水和-980集中运料巷15号孔底板出水进行突水机理研究。

The mine in north China is mainly threatened by the Ordovician limestone water.Xingdong Mine,located in north China,was affected by the occurrence conditions of its coal seam,seriously restricted by the high-pressure-bearing water of Ordovician limestone water while mining.In order to effectively prevent Ordovician water inrush in Xingdong mine,the water inrush mechanism was studied on the water inrush mechanism on the floor of 2127 working face,2222 and the floor of No.15 hole of -980 central transportation material roadway.
