摘要
通过构造当前工作点的三维球状缓冲区,并在缓冲区范围内进行空间搜索,实现断层等地质构造及高瓦斯聚集区等危险源信息的动态查询。利用井下空间对象三维建模、缓冲区分析等关键技术,在Longruan GIS 3.0基础上开发一套应用系统,实现缓冲区分析及其三维可视化,并使用煤矿实际数据进行检验。结果表明三维缓冲区分析是实现煤矿井下危险源查询的有效方法。
With the 3D spherical buffer zone of the current working place and with the space query in the area of the buffer zone, the dynamic query of the danger source information could be conducted in the fault, geological structure, high gassy accumulated area. With the 3D model establishing, buffer zone analysis and other key technology for the underground space objects, a set of applied system was developed base on the Longruan GIS 3.0. The buffer zone could be analyzed and could be in a 3D visualization with the applied system. The mine site measured data could be applied to inspect and check the system. The results showed that the 3D buffer zone analysis could be an effective method to the query of the underground mine danger sources.
