The Program Development and Application of Design Architectural Complex Protective Coal Pillar

Adopting the mathematic model of setting the protective coal pillar with vertical-line method, and on the basis of digitalized mapping and management system and VC++ platform, this paper develops a program suitable to the design of architectural complex, through which the designers can calculate boundary points’coordinates, area, volume and the quantity of unexploited coal by inputting the necessary parameters and the boundary points’coordinates of the protected objects, and can draw automatically the sketch map of protective coal pillar and the graphics drawn and can insert the maps into corresponding drawings through digitalized mapping and management system.
