充填接顶影响因素分析

Analysis on Influencing Factors of Roof-Contacted Filling

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。

Roof-contacted filling is an important way to achieve safe mining under seabed.Considering the properties of filling materials,filling technology,mining methods and ore-rock conditions based on the analysis of the influencing factors,a multi-level model was established by use of Analytic Hierarchy Process（AHP）,and a judgment matrix was constructed to determine the relative importance of the influencing factors.The factors influencing roof-contacted filling for mining under seabed in Sanshandao gold mine were analyzed and evaluated.The results showed that the properties of filling materials,filling pressure and the blasting technology are the main influencing factors of roof-contacted filling in this mine.
