| Abstract: | Based on simulation experiments taking the application of the sublevel caving in Zheng Zhou coal Administration as a pratatype example, this paper studies many the sublevel caving technique parameters such as the span of coal caving the spacing between the mouths of two coal caving tunnels the frequency of coal caving and soon. Some results in this study have been proved in practice. |
