摘　　要：针对目前大多数煤矿开采沉陷预计软件需要与CAD软件结合使用的现状,提出了开采沉陷预计数据存储、数据获取、数据组织和工程文件创建的新思路和新方法,运用CAD的Autolisp及VBA二次开发语言,研发了基于CAD平台的开采沉陷预计系统,使开采沉陷预计工作完全在CAD平台上操作和运行。详细分析了预计系统的主要特点和功能,展示了开采沉陷预计流程,并对该系统的工作面预计参数属性扩展、等值线绘制和带属性离散点参照块创建等关键技术问题进行了阐述。研究表明:该系统在基础数据获取、数据组织、数据库建立和工程文件创建上实现了最大程度的集成化、自动化和便捷化,有效解决了不同工程数据之间无法快速联合运算的问题;同时,该系统绘制各类建(构)筑物保护煤柱线、绘制移动变形曲线等辅助功能为"三下"采煤研究工作提供了便利。In view of the current situation that most of the mining subsidence prediction software needs to be combined with CAD software,this paper puts forward new ideas and methods for data storage,data acquisition,data organization and engineering file creation of mining subsidence prediction.Using Autolisp and VBA secondary development language of CAD,a mining subsidence prediction system based on CAD platform is developed.The system enables the prediction of mining subsidence to be operated and worked entirely on the CAD platform.The main features and functions of the prediction system are introduced in detail,the prediction process of mining subsidence is displayed,and the key technical problems of the system are expounded,such as the extension of the predicted parameters attributes of the working face,the drawing of contours and the creation of the discrete point reference block with attributes.The study results show that the system achieves maximum integration,automation and convenience in basic data acquisition,data organization,database establishment and engineering file creation,and effectively solves the problem that different engineering data can not be quickly combined;at the same time,the auxiliary functions of the system,such as drawing protective coal pillar lines of various buildings and structures,drawing movement and deformation curves,provide convenience for the research work of "three-under" coal mining.
