摘要
基于实测资料建立了极不充分开采条件下概率积分法预测参数计算表达式和深部开采时下沉系数计算式，为深部开采地表移动预测提供了计算方法；基于极不充分开采的定义，给出了深部开采大采宽条带的设计及控制地表沉陷的方法．
Practice and test show that strata movement is controlled by hard strata. Only when mining width is large enough to make the hard strata crack, will the surface movement increase obviously. The mining which doesn’t make hard strata crack is called ultra subcritical mining. Based on the field data, the formulas of calculating the parameter of probability function method in ultra subcritical mining and subsidence coefficient in deep mining were established. These supply a method to predict surface movement in deep mining. From the definition of ultra subcritical mining, the methods of designing mining width and strip size and controlling surface subsidence in deep mining were given.
