Abstract In order to transfer the paste filling material made from the ground filling station to the goaf area of the underground working face, paste filling underground and mining was designed. Holes, wear-resistant pipes, wall filled with cement paste, fixed wear-resistant pipe and a series of processes were put forward. During the construction, multi-level drilling and hole reaming, floating sinking method, wear-resistant pipe and PO42.5 portland cement wall filling were used to achieve good construction quality. At the same time, the difficulties encountered in the construction process of the feeding were solved, providing a reference for the same type of engineering construction.
