充填接顶是实现海底开采安全的一个重要途径,在对其影响因素分析的基础上,考虑充填料性质、充填工艺、开采方法和矿岩性质等条件,采用层次分析法,建立了充填接顶影响因素分析多层次模型,并据此构造判断矩阵来确定相关因素的相对重要性。对影响三山岛金矿海底开采的充填接顶因素进行了分析评价,结果表明充填料性质、充填压力和爆破工艺是影响矿山充填接顶质量的最主要因素。 Based on the analysis of influencing factors, considering the nature of filling material, filling technology, mining method and properties of ore and so on, the method of AHP is adopted to establish the technology of filling and roofing The multi-level model is used to analyze the influence factors, and the judgment matrix is ​​constructed accordingly to determine the relative importance of the relevant factors. The factors influencing the seabed mining overcapacity in Sanshandao Gold Mine are analyzed and evaluated. The results show that the nature of charge, the filling pressure and the blasting process are the most important factors affecting the quality of the top-fill of mines.
