The finescontent and kink index of fiber obviously decreased while the fiber length and fiber coarseness increased.

The results showed hydroxyethylated pulp has higher resistance to beating than origin pulp. The reasons rested with the change of fiber shape, hemicellulose content and finescontent.
The experimental data indicated that it is possible to increase the finescontent in the fill, thus utilization coefficient of tailings is raised and properties of fill will be improved.
