Abstract	In mine exploration, phenomenon of floor heave is the main feature of swelling rock roadway destruction, and floor heave may cause great difficulty for roadway supporting. As every mechanism of floor heave has a certain application scope, so, based on a specific engineering environment, it is necessary to investigate treatment technique. In process of floor heave treatment of Fenjin coal mine in Henan province, by simplifying bearing mode of complex stress about swelling rock, simple and practical computational mechanic model is established to analyze the problem, and two-gunite-one-anchorage support technology is tested. Practice shows that support technology of two-gunite-one-anchorage can guarantee stability of roadway, and it has good popularization value.
