金星岭—80m2#东底柱采场空高的测量

HEIGHT SURVEYING OF COLLAPSED VOID OF 2~#E BOTTOM-PILLAR STOPE AT-80m JINXINGLING

采用前方交会法和三角高程测量法 ,在金星岭 -80m 2 #东底柱采场 ,测量FDQ采场残矿冒落空高 ,并分析前方交会法水平边长精度和三角高程测量采场空高精度。结果表明 ,能准确地测出采场空高和计算采矿量 。

Height measurement of collapsed void of 2 #E bottom pillar stope at -80m Jinxingling is carried out by using the methods of forth intersection and triangulation leveling and the measuring accuracy is analyzed.The results of 12 group data show that the method works with high accuracy for mining void.
