白象山铁矿东西大巷突水因素与防治措施剖析

白象山铁矿是极复杂富水难采矿山，大断层、隐伏小断层、裂隙节理及封堵不良钻孔等突涌水因素危害矿床开发。以-495 m水平东西大巷的展布为出发点，充分挖掘现有地质资料绘制了两大巷纵剖面图，重点对大巷在含水层掘进及与断层交汇的突水危险性进行了剖析，探讨了在高断层水压条件下探水防水的方法技术。同时，结合封堵不良钻孔的深度特征、分布状况及突水机理，有针对性地提出直接封堵和间接封堵两种封堵方式。以期为白象山铁矿基建和开采以及国内类似矿山提供参考。

Analysis of Water Inrush Factors and Control Measures for the East and West Haulageways in Baixiangshan Iron Mine

Baixiangshan iron mine is an extreamly complex water-rich deposit. Its large faults,small insidious faults,joints and fissures,and the badly sealed drilling holes all contribute to water inrush that is endangering the mining. The longitudinal diagram of the east and west -495 m haulageways were drawn based on the available geological data. The paper highlights the analysis of the risk of water inrush when a haulageway pierces in the aquifer and intersects a fault,and the discussion of the technology of wate...
