摘要
针对高阳铁矿赋存条件,应用矿床水体下开采理论和数值模拟计算方法,研究了该矿开采时的覆岩破坏规律,提出了符合高阳铁矿的裂隙带预计公式,论述了采用充填采矿方法的可靠性,推荐矿山采用浅孔房柱嗣后充填采矿法和有底柱分段空场嗣后充填采矿法,提出了安全回采措施和防治水措施。
In light of the occurrence conditions of Gaoyang iron deposit, the theory of deposit mining under water body and numerical simulation calculation method are used to study the destruction law of overlaying rock in mining. The fissure belt prediction formula conforming to Gaoyang iron deposit is proposed and the reliability of adopting the mining method with filling is expounded. It is recommended for the mine to use the shallow-hole room-and-pillar mining with delayed filling and the sublevel open stoping with pillars and delayed filling, and the measures for safety extraction and water prevention and control are suggested.
