内蒙古某矿井灰岩底板承压水分区防治研究

Study on Prevention and Cure of Confined Water Area of Limestone Floor in a Mine in Inner

为避免矿井底板灰岩承压水突水事故,本文在前人研究的基础上,结合内蒙古某矿井的地层、构造及水文地质特点,研究底板灰岩岩溶水的赋存特征,并总结矿井涌水量、突水量特征及影响因素,最终确定导水裂隙带分布特征及分布位置,提出灰岩底板分区防治措施,为矿井安全生产保驾护航。

Based on the previous studies and combined with the strata, structure and hydrogeological features of a mine in Inner Mongolia, this paper studies the occurrence characteristics of karst water in the bottom limestone and summarizes mine surge Water quantity, water inrush characteristics and influencing factors, and finally determine the distribution characteristics and distribution of water-conducting fractured zone, put forward prevention and control measures of limestone floor subzone, to protect mine safety production.
