采场测量
surveying in stope

  ea一ehang eellang采场测且(surveying in stope)采场回采矿石阶段的测量工作。采场测量的目的是绘制采场的平面图、纵投影图和断面图,以统计矿石产量和计算矿石损失率和矿石贫化率。采场测量包括:(l)根据采准巷道和采场内的控制点标定采场位置、炮孔位置、验收和填图。(2)测量采场的轮廓并填图。 随着.矿体赋存条件和采矿方法的不同,采场测绘方法也异,分为人员能进人的采场测量、深孔刚量和采场空周测量。人员能进人的采场测量分为两种情况:(l)矿床较窄,用浅孔留矿法开采时,形成狭长采空区,在两天井间敷设经纬仪或罗盘仪导线,用支距法测量采场轮廓。并绘制采场平面图、断面图和纵投影图等(图1)。(2)采场较宽大时,采用极坐标法,用经纬仪、平板仪或罗盘仪进行测绘,通过天井把导线点引入采场,建立控制点I、I、兀、份(图2)。在l点安置经纬 纵投影图A一A断面图经 图1留矿法采场图姐分 图2宽大采场测t仪,后视l点,依次测量采场各轮廓或顶底板各特征点的坐标和高程,最后绘制采场图。
