胡家河煤矿涌水特征及规律分析

Analysis on water inflow characteristics and law of Hujiahe Coal Mine

提前掌握和准确预测新开采工作面的涌水量情况,对于做好煤矿防治水工作,防止和减少事故,保障职工生命安全和健康意义重大。为了研究矿井的地层、煤层、构造分布发育规律,查清矿井的水文地质特征、充水水源、充水通道、充水强度、水文地质条件,收集矿井开采以来各个工作面的实际涌水量情况,分析各个回采工作面之间的相互影响关系,总结归纳各个工作面之间的相互影响规律,为规划工作面开采时的防治水工作提供参考和依据,确定矿井未来规划工作面回采过程中防治水工作的重点。通过矿井以往各个工作面之间的涌水量及相互影响规律,以期用比拟法预测规划工作面的涌水量。

Mastering and accurately predicting the water inflow in the new working face is great significance to the prevention and control of water in coal mines,preventing and reducing accidents,and ensuring the safety and health of employees.In order to study the distribution and development law of strata,coal seams and structures in the mine,and find out the hydrogeological characteristics,water filling source,water filling channel,water filling intensity and hydrogeological conditions of the mine,the actual water inflow of each working face is collected;the mutual influence relationship between the various mining faces is analyzed;the mutual influence laws between the various working faces are summarized,and the key points of water prevention and control work in the mining process of planned working face in the future are determineed,which can provide reference and basis for water prevention and control work in planning working face.Based on the water inflow between various working faces of the mine and the law of mutual influence in the past,it is expected to predict the water inflow of the planned working face by the analogy method.
