大比例尺数字矿图转换与缩编

Conversion and Reduction of Large Scale Digital Ore Map

杨庄煤矿3煤层有两个采区,原3煤层图纸分采区单独绘制1:2000采掘工程平面图,现因采掘接续调整,需要绘制3煤层全矿井采掘工程平面图,因图幅较大,不利于打印输出,为此两采区图纸合并后进行了转换与缩编,以达到快速成图的目的。

There are two coal mining areas in the 3 coal seam of Yangzhuang Coal Mine. The original 3 coal seam drawings separate mining area separately plotted 1:2000 mining plan. Due to the adjustment of mining and mining, it is necessary to draw the 3 coal seam mining plan for the whole mine. Because the larger map is not conducive to printout, the two mining area drawings have been transformed and downsized after merging, so as to achieve the goal of rapid mapping.
