摘要
介绍了鹤煤六矿在-600m北大巷贯通测量中,通过使用陀螺经纬仪定向、井下三架法导线测量与红外三角高程代四等水准测量相结合的技术进行矿井水平大巷贯通测量,有效控制了测量精度,取得了良好的效果。
Abstract The breakthrough survey in --600 m north main roadway in No. 6 Coal Mine ot Hebi Coal Industry Group was introduced. The gyro theodolite was applied to orientation, and the breakthrough survey for the horizontal main roadway in the coal mine was carried out by the combined technologies of tripod method in traverse surveying and infrared trigonometric leveling replaced fourth-grade leveling method. The measurement accuracy was effectively controlled and a favorable effect was obtained.
