摘要
隐伏岩溶陷落柱突水是威胁矿山安全开采的极大隐患。范各庄矿属于水文条件极复杂型矿井,井田内已发现了12个岩溶陷落柱,物探工作在探查陷落柱发育及保证煤矿安全开采过程中发挥了不可替代的作用。
Sudden flooding from karst subsided column constitutes a great threat to coal mining safety. Hydrogeological conditions of Fangezhuang Coal Mine is terribly complex . Twelve karst subsided column have been found. Geophysical prospecting is so important that cannot be replaced in exploring distribution and coal mine safety.
