Abstract: According to the comprehensive study on the formula of drawing theory and indoor drawing test, the reasonable stope structure parameters of non-pillar sublevel caving mining method in Jianshan Iron Mine were obtained. It guarantees the production of mine, and reduces the loss and dilution index. Meanwhile, it provides the proof for preliminary design and construction. 
