近代化矿井往往是多水平同时开拓,其巷道纵横分布,错综复杂。为了解各巷道相互间的空间位置,通常把各水平的巷道垂直投影在一个水平面上而绘成巷道平面图(如图1就是一张具有三个水平的巷道综合平面图)。很显然,在综合平面图上避免不了有部分巷道重叠起来,分不清层次,难于明了其空间相互位置,在急倾斜矿床中尤为显著。为此,需要有明显的富有立体感的图来表示矿山的开拓、运输、排水、通风等系统。也可以用立体图来表示建筑物的基础和某些复杂的工艺流程。

Modernized mines are often open at the same time and at various levels, with vertical and horizontal distribution of the roadways and complexities. In order to understand the spatial location of each lane, it is common to project the horizontal laneways vertically onto one horizontal level to form the laneway plan (Figure 1 is a three-level laneway plan). Obviously, in the comprehensive plan can not avoid the overlap of some tunnels, can not tell the level, it is difficult to understand the spatial mutual position, especially in steep deposits. To this end, we need to have a clear three-dimensional map to represent the mine development, transportation, drainage, ventilation and other systems. You can also use a perspective view of the building’s foundation and some complex processes.
