System composition and related algorithm principle
1.1 system composition
Three mining under ground deformation is expected to change by data management,system
Shape computation,graphics,working face design,system management five modules
Composition.
Data management module mainly realizes face data,calculation of parameters,
Surface calculation scope and the calculation results of the inquiry,add,delete,modify,
Print functions,and provides the mining data input and digital manual
Type 2 ways.
The deformation calculation module function is to choose the working face and surface calculation
Range is expected,and with visual subsidence and displays the results,
Provide calculation results report output function.
Graphics processing module's main function is according to the deformation calculation results
Rendering graphics,including isoline,vector diagram,surface figure 3 kinds of graphics,
And can edit graphics on.
The main function of mining design module is auxiliary face asher
Plan,in the face of mining previously predicted after all kinds of surface mining shadows
Ring degree,calculating the best face design scheme.
System management module's main function is to system database
Maintenance and management.
1.2 calculation model
Three mining under ground deformation expected system can use a variety of subsidence
Expected algorithm.Based on probability integral method for example paper gets surface subsidence
Millions of theoretical model.
