Abstract:Based on the Dimine digital mining software, an intelligent tunnel excavation engineering blast-hole design system was developed by using computer graphics and object-oriented technology to solve the problems of low efficiency and tedious modification of conventional manual and CAD blasting-hole design methods. According to the blast plan and tunnel excavation data, the type and location of blast-hole can be determined by using the quadtree algorithm, the blast-hole can be modified, numbered, lined and charged through data editing, the coordinate dimension of the blast-hole can be achieved and the overlap dimension can be avoided by using coordinate transformation. Finally, the blasting-hole layout charts and blasting parameter charts which are adjusted to practical engineering are output. Its application shows that this system improved the design efficiency of both blasting-hole and blasting charts in tunnel excavation engineering.
