随着充填技术在地下矿山的普遍应用，充填工艺及设备的选取对充填效果影响尤为显著。目前，高浓度全尾砂充填技术存在着充填体泌水少、接顶率高等特点，广泛受到矿山的青睐。以安徽大昌矿业集团有限公司吴集铁矿(南段)为例，通过对其充填站生产工艺流程及运行过程中所遇到的问题进行综合分析，然后对充填系统进行技术改造试验，指出气水结合方式是解决卧式砂仓流动性的有效途径。结合试验情况并根据尾砂物理性能、砂仓几何参数等，对充填站的造浆系统进行改造，将砂仓沿长度方向划分为造浆区、搬运区、堆砂区3个区。改造后的砂仓不仅解决了堵管问题，使得放出的砂浆浓度较稳定，而且消除了大量尾砂堆积在砂仓内的问题，提高了砂仓循环使用率，保证了充填体的质量，降低了充填成本；改造后的砂仓具有流程简单、可操作性强等特点。通过对卧式砂仓的造浆改造、使用，采用气水结合的方式，实现了大产能连续充填。

With the filling technique widely used in underground mines,the selection of filling process and equipment in-fluencing the filling effect is particularly significant. Currently,high concentration of whole tailings backfill technique owns fea-ture of less water bleeding,high rate of roof contact etc,which are widely favored by mining enterprises. Taking Wuji Iron Mine of Anhui Dachang Mineral Product Trade Co. ,Ltd. ( southern section) for example,a comprehensive analysis on the problem on its production process and the process of filling stations in operation encountered is carried out,and then technological trans-formation tests on the filling system are taken. It is drawn that the air and water combined approach is an effective way to solve the horizontal sand liquidity. Joint with the tests and in accordance with the physical properties of the tailings,and the geomet-ric parameters of sand silo,the mud system of filling stations was transformed to divide the sand silo into three zones along the length of the sand silo,namely mud area,handling areas,and heap sand area. After the transformation of sand silo,the problem of plugging is solved which makes a more stable release of mortar concentration,and the sand tailings accumulation in the stor-age is eliminated,by which the recycling rate of sand silo is improved,the quality of the filling body is ensured and the cost of filling is reduced. What's more,the sand silo has characteristics of simple process and high operability after the transformation. Through the mud transformation and usage of horizontal sand silo,a combination of gas and water can achieve large-capacity continuous filling.
