Abstract：The dam filling materials of transfer pool in Menkeqing coal mine uses coal gangue and fine sand. In order to get the relative density of meeting the specification requirements after the filling materials compaction, research should be determined by dam filling test. Test is divided into indoor geotechnical test and the field rolling test. Through the indoor test the author works out the content of coal gangue P5, dry density ρd, relative density-Drthree factors relevant figure, obtains the relative compaction parameters of coal gangue and fine sand with the filling standards under the optimum filling ratio through the field rolling test.Taking waste material coal gangue as the main filling materials to reinforce the transfer pool not only can make full use of waste resources, but also can reduce coal gangue harm to the environment, which have very good application prospect and provide reference for similar projects.
