A Primitive Blocking Study of Reserves’ Graphs Using Computer-Aided Design

Abstract:

All kinds of mining enterprises prefer to use computer-aided design (CAD) in drawing figures of mining reserves. CAD is convenient to operate and ensures the creation of intuitive and beautiful figures. However, CAD causes data error easily due to human intervention. Moreover, CAD wastes time and is prone to omit records. To reduce the incidence of such errors, the current paper examines the transformation of CAD-drawn reserves’ figures and databases into “block” form. This paper also aims to realize the conversion of figure blocks and databases using Visual Basic (VB) in CAD and database applications. To achieve this result, the circle and text are first extracted from CAD form. Then, a series of changes is implemented. Lastly, figure blocks are endowed with new properties. Using this approach can quickly transform figure elements into block properties, achieving good application effects.
