庆阳正南煤田矿井涌水量预测及煤田水害防治对策

摘要

Based on the existing geological and hydrogeological data,the author studied the hydrogeological characteristics of Zhengyang coal mine in Qingyang District.According to the program of coal development and utilization coal exploitation,the conditions and%以矿区现有地质—水文地质资料为基础,通过分析矿区水文地质特征,结合煤田开发利用方案,初步论证了正南煤田煤矿矿井充水条件和因素,并采用＂大井＂法预测了矿井用水量,提出了正南煤田开发利用过程中煤田水害的防治措施,以期为该煤矿建设开发提供依据。
