【摘要】：针对煤矿企业需求简单实用的矿井三维数字化立体模型系统,本文在VB环境下,对AutoCAD进行二次开发,采用从矿井二维平面图纸提取数据信息、三维空间立体场景建模、计算机编程语言和Access数据库等技术手段成功的开发了矿井三维数字化立体模型系统,实现了矿井三维立体模型的动态创建及信息化管理,实现了矿井工程图纸由二维形态上升到三维数字化形态的快速转换。矿井三维数字化立体模型能清晰的呈现出整个矿井的实体形态,远观可观察整个矿井巷道和工作面分布的空间格局,近观可达到清晰识别局部巷道交错的层位关系。基于矿井三维数字化立体模型,对回采工作面模型进行了三角形分割,构建了回采工作面实时进度和产量数字化计算模型,在系统模块下可实现实时产量的计算,同时给出了以天数为变量的巷道预测变形值函数表达形式,借助矿井三维数字化立体模型系统平台,可将巷道变形信息在相应的模型巷道上清晰显示并实时更新,基于矿井三维立体模型与实体矿井的1：1尺寸对应关系及空间精准的三维坐标吻合关系,构建了人员空间位置实时闪烁定位显示模型,获知井下人员的三维坐标即可在矿图模型上快速定位到该人员所在位置,当井下灾害发生时可快速进行井下最优救援路线分析,为减少矿山人员及财产损失提供必要的决策支持。研究成果在安徽张集矿得到了试验应用,验证了研究成果的正确性和实用性,对于矿井的安全高效生产、信息化矿井建设和智能决策具有重要的借鉴意义。
