采空区顶板安全厚度预警预报系统研究与开发

Research and Development of Prediction and Forewarning System of Goaf Safe Roof Thickness

基于薄板理论,提出一种新的采空区顶板临界厚度计算公式。并以此为核心,结合现场实际需要,采用面向对象编程思想,使用Flex技术,开发了一套采空区顶板安全厚度预警预报系统。该系统实现了空区信息的搜集和录入,完成了空区信息的整理以及维护,直观显示空区详细信息,并能重点分析空区的危险程度且能及时报警。该系统在某矿山采空区的预警预报中取得了很好的效果。

A new kind of calculation formula of goaf roof critical thickness was proposed based on thin plate theory. Used it as the core, a set of prediction and forewarning system of goal safe roof thick- ness was developed combined with site actual requirement and adopted object-oriented thought and using Flex technology. Collection and input of goaf information are realized in this system, arrangement and maintenance of goaf information are completed, which could display goaf detailed information visually, and it can emphatically analyze the danger degree of goal and alarmed in time. This system gets good effects in prediction and forewarning of a mine goal.
