When the structure parameters of upward horizontal sub-level drift fill stoping methods are bigger,the stoping efficiency is higher,but the stope stability can not be guaranteed because of the excessively large structure parameters,the optimization focus of stope structure parameters shall be on the selection of drift cross-sectional dimension.The numerical simulation and Mathews stability graphical analysis were carried out from the aspects of the economy,rational exploitation of resources,and the drift cross-sectional dimension was recommended finally.
