Abstract:At present, the mines in our country gradually shift from the shallow mining to the deep mining, but the deep well floor is particularly serious hazard by high pressure underground water.This article considers the high pressure underground water as three-dimensional transient flow, sets up mechanical model by combining mechanical knowledge and to analyze the destructive action on floor from two aspects. On the one hand, researching the impact destruction of high pressure water at different positions of floor ;… Show more
