Abstract: The ceramic composite pipe used in the filling pipeline network of the Dayingezhuang Gold Mine has some disadvantages such as great self-weight and complicated connection. Based on the calculation and analysis of the filling system in the Dayingezhuang Gold Mine， the reliability of the application of the ultra-high molecular weight polyethylene pipe connected with flanges in the local filling pipeline network of the mine is verified， which provides a basis for the subsequent optimization of the filling pipeline network.
