兔窝沟煤矿水文地质条件特征及其对矿山生产的影响

Characteristics of Hydrogeological Conditions in Tuwogou Coal Mine and Its Influence on Mine Production

矿山生产过程中,原生地质条件发生较大变化,导致矿山安全条件发生变化,伴随着矿井生产年限增加,水害对矿山安全生产的威胁日益增加。本文详细阐述了兔窝沟煤矿水文地质特征,认真划分了含水层、隔水层,对矿井的补径排条件和充水因素进行了分析,并通过不同方法模拟计算了矿井导水通道的发育情况及矿井未来5年的涌水量,指出了矿山生产过程中需要采取的必要措施,为矿井安全生产奠定了基础。

In the process of mine production,the primary geological conditions change greatly,which leads to the change of mine safety conditions.With the increase of mine production years,the threat of water damage to mine safety production is increasing.This paper expounds the hydrogeological characteristics of Tuwogou coal mine in detail,divides the aquifer and aquiclude,analyzes the water replenishment,drainage conditions and water filling factors of the mine,simulates the development of the mine water channel through different methods,calculates the mine wa‐ter inflow in the next five years.It points out the necessary measures to be taken in the mine production process,laying the foundation for mine safety production.
