矿图是煤矿生产过程中不可少的重要图纸资料。现行矿图是根据各测点的坐标x和y定出各点在平面上的位置,并用数字注记各点高程的标高投影法绘制成图的。用此法绘制的缓斜及水平煤层采掘工程平面图具有作图方法简单、便于度量的优点。但在急倾斜煤层由于煤层倾角大、采区上山眼附近巷道集中,致使巷道在平面图上的投影位置重叠,采掘情况无法表示,巷道关系难以区分,给绘图及读图造成困难。 根据我矿急倾斜煤层开采的巷道布局,采用轴测投影法将采区上山处的沿煤层倾斜方向剖面图改绘成立体图,既保证了剖面图 Mine map is an important mine during the production of important drawings and materials. The current mine map is based on the coordinates of each measuring point x and y to determine the location of each point in the plane and digital elevation of each point of elevation projection method to map. The plan of gently inclined and horizontal coal seam mining project drawn by this method has the advantages of simple drawing method and easy measurement. However, due to the large dip angle of coal seam in steeply inclined coal seams, the roadway near the mountainous eye of the mining area is concentrated, which leads to the overlap of the projection positions of the roadway on the floor plan. The excavation situation can not be indicated and the roadway relationship is indistinguishable, which makes drawing and drawing difficult. According to the mine roadway layout of steep seam mining, using the axonometric projection method, the section along the seam slope in the up-hill mining area will be redrawn into a stereogram to ensure the profile
