井巷掘进工程炮孔智能设计系统

 针对传统的手工及CAD 炮孔设计效率低、修改繁琐等问题，基于Dimine 数字矿山软件，应用计算机图形学、面向对象编程技术，开发了一种智能化的井巷掘进工程炮孔设计系统。该系统可根据井巷掘进工程的爆破方案及有关数据，通过点-四叉树索引算法实现炮孔类型及位置的布设，通过数据编辑实现炮孔的修改、编号、连线和装药设计；通过坐标转换实现炮孔的尺寸标注，同时还可移动标注线避免线条重叠，最终输出适用于实际工程的炮孔布置图和爆破参数表。工程实践表明，该系统有效地提高了井巷掘进爆破工程中炮孔和爆破图表的设计效率。

Intelligent Blasting-hole Design System in Tunnel Engineering

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.
