摘要
近年来块石胶结充填法以其充填效率高、充填成本低等优点,迅速在国内外得到广泛应用。但该充填工艺尚主要用于急倾斜厚大矿体,充填料为垂直下放。中国倾斜薄矿体在金属矿山中占有较大的比例,而此类矿床应用块石胶结充填时其充填料下放特性和充填工艺与厚矿体的相比,有很大的差别。本文针对所述问题,在峪耳崖金矿采用正交试验方法,进行了现场模拟试验,并对试验结果及主要影响因素进行了分析,在此基础上,推荐了合适的材料配比与合理的充填工艺。
In recent years waste cemented fill mining method was rapidly and widely introduced in internal and external mines because of its many advantages such as high filling effeciency, low filling cost etc. But this mining method is mainly suitable for steep dipping thick and large ore bodies where vertically downword transport of filling material is possible. Steep inclined thin ore bodies have a large proportion in metal mines in China. When utilizing waste cemented filling in thin ore body mining, downward transport charactdri-stics of filling material and filling technolorgy are quite different from those in thick ore body mining. In Yuerya gold mine field simulating test was conducted with orthogonal test method, and the results and main influence factors were analysed. On the basis of this rational fill composition and rational filling technolorgy were recommended.
