摘要
以山西长治郊区三元南耀吉安煤业有限公司2506回采工作面巷道贯通测量为例,对巷道测量控制点偏心改正测量技术的应用进行了研究。该巷道贯通测量由于架设单体支柱而造成原有测量控制点无法通视,采用偏心改正测量技术,将测量点位偏移,避免了从上一测量点重新引测或迁移单体支架的问题,提高了测量效率,保证了测量精度。在巷道贯通测量精度评定中,该矿2506回采工作面巷道贯通测量导线闭合差为1/11 024,方位角闭合差为+28′26,高程坐标闭合差为+0.048 m,该技术取得了较好应用效果。
Taking the roadway penetration survey in 2506 mining face of Sanyuan Nanyao Ji'an Coal Industry Co.,Ltd.of Changzhi Suburb of Shanxi as an example,this paper studied the application of eccentricity correction measurement technology for roadway survey control points.The original survey control points could not be seen in the roadway penetration survey due to the erection of single support.The eccentricity correction measurement technology was used to offset the measurement points,avoiding the problem of re-directing or migrating the single support from the previous measurement point,improving the measurement efficiency and ensuring the measurement accuracy.In the evaluation of the accuracy of roadway penetration measurement,the closure error of the surveying traverse was 1/11024,the azimuth closure error was+28'26,and the coordinate closure error of height was+0.048m in 2506 mining face of the mine.The technology has achieved good application results.
