Abstract

In recent years, based on that the research and application of the open stoping with subsequent fill continuous mining method of "two step" model is getting more and more attention. The design of the strength of cementing filling body of the first step ore room is especially important under the condition of the continuous mining. In the paper, the formula of the strength design of cementing filling body was deduced by analyzing the force state of cementing filling body that influenced by lateral pressure of tailings of the second step ore room, the influencing factors that influenced the required strength of cementing filling body and their relationship were fully considered, including the structure size of cementing filling body, the friction between surrounding rock and cementing filling body and the lateral pressure of tailings. Pointing out the influence of the lateral pressure of the bulk mass tailings filling body to the stability and strength design of cementing filling body can’t be ignored in the design. There is high practical guiding value to engineering design of the model.
