Multifunctional and novel filling material adopting iron ore whole tailings

The invention provides a multifunctional and novel filling material adopting iron ore whole tailings. The multifunctional and novel filling material is mainly prepared from the iron ore whole tailings, cement and water in the weight ratio being (57-63):(10-15):(27-29). The multifunctional and novel filling material adopting the iron ore whole tailings adopts simple formula, is low in cost, higher in setting rate and better in compressive strength and workability, facilitates construction and can be used for filling goafs of mining areas and filling water seeping cracks in mines. 本发明提供种多功能铁矿全尾砂新型充填材料，主要由铁矿全尾砂、水泥、水按照57-63：10-15：27-29的重量比制备而成。本发明提供的多功能铁矿全尾砂新型充填材料配方简单、成本低廉、施工方便，凝固速度较快，抗压强度和和易性均较好，可以用于矿区采空区的充填，也可以用于填补矿井内的渗水裂缝。
