The ceramic composite pipe used in the filling pipe 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 pipe network of the mine is verified,which provides a basis for the subsequent optimization of the filling pipe network.
