大型矿山通常有复杂的巷道系统,传统的平面设计难以清晰表达巷道之间的空间关系,使工程技术人员不能直接获取巷道系统的空间分布特征。本文尝试采用三维建模进行巷道的空间优化布置,将其分解为断面设计和轴线设计,采用拖拉的方法生成巷道的三维实体模型。借助地理信息系统中的空间分析方法,建立巷道模型与轴线、断面之间的连接关系,借助该连接关系,提出一种三维巷道的空间最短距离的近似计算方法,即先计算轴线之间的空间最短距离,然后再减去两端截取部分,可得到空间任意巷道之间近最短近似距离。最后,将该方法应用于安徽某煤矿工程。
Large-scale mines usually have complex roadway systems. It is difficult to clearly express the spatial relationship between roadways by traditional graphic design, so that engineers and technicians can not directly obtain the spatial distribution characteristics of roadway systems. This paper tries to use 3D modeling to optimize the spatial layout of roadway, decomposes it into cross-section design and axis design, and uses drag-and-drop method to generate 3D solid model of roadway. With the aid of the spatial analysis method in GIS, the connection between the roadway model and the axis and the cross section is established. Based on the connection relation, an approximate calculation method of the shortest distance in 3D roadway is proposed, that is to calculate the space between axes Shortest distance, and then subtract the intercepted part at both ends to get the shortest approximate distance between any roadways in the space. Finally, this method is applied to a coal mine in Anhui Province.
