车集井田太原组上段灰岩富水性分析评价

Analysis and Evaluation of Water Abundance of the Upper Taiyuan Formation Limestone Water in Juji Coal Field

在收集车集井田水文地质资料的基础上,对太原组上段灰岩赋存情况及富水性进行分析评价。研究表明,太原组上段灰岩含水层对井田开采二2煤层有一定影响,在矿井生产过程中必须采取底板注浆加固等相应措施,防止水害事故发生。

Based on collecting hydrogeological data of Juji Coal Field,the occurrence of the upper Taiyuan formation limestone and water abundance of limestone water was analysed and evaluated.Research shows that,the aquifer of the upper Taiyuan formation limestone has certain influence to the mining of Ⅱ2 coal seam,and relevant countermeasures must be carried out to prevent water damage accidents,such as floor grouting reinforcement,and so on.
