Section Line Calculation Software Development of Surface Subsidence Speed in Coal District

About five indexes were used to described and analyzed coal district surface subsidence principle,which include surface subsidence,horizontal movement,surface incline,curvature and surface horizontal deformation.With high-efficient mining development of coal mine,rapidly mining leaded to rapidly surface subsidence,so objects needed to be protected on surface,but the parameters 'surface subsidence speed' was applied to studied seldom.On the basis of 'surface subsidence speed' meaning,and it act as mathematics model of software development,section line calculation software of surface subsidence speed in coal district was developed,some functions were put forward,and the software offered convenience for studying of surface subsidence speed principle of coal district.
