金桥煤矿井筒变形实时测量与井筒破坏突变模型

摘要

According to the factual problem of shaft deformations due to assistant shaft water of Jinqiao coal mine，it has studied the real time observation of shaft’s movement non-linear and deformation by GPS and applied cataclysm theory to build a cataclysm model of shaft damage．Some expression patterns of control and state variables of shaft deformation，which give us a significant guidance of effective dealing with shaft damage have been presented．%针对金桥煤矿副井涌沙引发井筒变形的实际问题，研究了采用GPS技术实时监测井筒动态非线性变形方法；运用了突变理论，建立了井筒破坏的突变模型；给出了井筒变形的控制变量与状态变量表达式；对有效地治理损害的井筒具有重大指导作用．
