摘要
根据矿山压力控制理论。材料力学理论及几何损伤力学理论，提出了煤矿底板突水的力学模型，推导了该模型下底板岩梁应力计算公式，分析了底板损伤突水机理．
On the basis of the theories of underground pressure control, material mechanics and the geometrical damage mechanics, a mechanics model of floor outbursting in coal mines is put up, the formula to calculate normal stress in floor beam is given, arid the mechanism of floor damage outbursting is analyzed.
