The invention provides a method for filling a goaf with different materials alternately. The advantages of paste filling and super high-water material filling are integrated, and purposes of reducingthe filling cost, improving the filling efficiency and achieving the level of more than one million tons per year are achieved on the basis of ensuring the ground filling effect to the maximum extent.According to the specific implementation scheme, the method for filling the goaf with different materials alternately in the invention comprises the following step: filling the same filling working face of the goaf with a plurality of filling bags, wherein the filling bags comprise a plurality of paste filling bags and a plurality of super high-water material filling bags. 本发明提出了一种采空区不同材料交替充填方法，综合膏体充填和超高水材料充填的优点，在最大限度的保证地面充填效果的基础上，实现降低充填成本，提高充填效率，达到年产百万吨以上的水平。本发明的一种采空区不同材料交替充填方法，其具体实施方案如下：在采空区的同一个充填工作面内利用多个充填包进行充填，多个充填包包括多个膏体充填包和多个超高水材料充填包。
