【摘要】 随着矿井生产规模扩大,现有水文地质条件研究已经不能满足安全生产需要,导致在矿山开采过程中遇到不同程度的的突水,严重影响开采工作.因此,深入研究影响矿井安全生产的主要水文地质因素对矿井水防治工作至关重要.通过巷道节理统计走向玫瑰花图对矿床构造节理发育进行判断,进一步分析充水水源与裂隙发育方向的联系;运用派珀三线图法对离子运移规律进行分析来判别矿井水源;运用解析法对矿井涌水量进行预测.从理论上掌握矿井突水水源补给来源主要为基岩裂隙水、涌水通道为基岩裂隙和涌水量大小.通过上述理论方法对李楼铁矿水文地质条件研究能够取得了比较满意的效果.更多还原

【Abstract】 Along with the expansion of the mine production,the currently hydrogeological conditions can’t meet the needs of the production safety,which will lead to water bursting in the process of tunneling and affect the mining work.Thus,a thorough study of the main hydrogeological factors which affect coal mine safety in production is very important.The paper,by joint statistics of roadway,figures out the rose to determine deposit structure joint development.It further analyzes the relation between water filling and fracture direction; it uses the method of three piper diagram analysis of ion migration rule to discriminate the water source of mine,and uses the analytical method to forecast mine water inflow.Theoretically speaking,it grasps mine water inrush water supply source mainly for bedrock fissure water and the bedrock fissure water channel and water inflow.The hydrogeological conditions in Lilou iron mine can achieve satisfactory effects through the above theoretical methods.更多还原
