张双楼煤矿大型贯通工程实践总结

Summary of practice of large scale penetration engineeringin Zhangshuanglou Coal Mine

多年来煤矿测量技术更新变化不大,《煤矿测量规程》长期未修订,已不满足当前矿山测量需求。通过系统总结张双楼煤矿12年来6个大型贯通工程实例,在使用现行精度仪器情况下,采用“四架法”测量工艺,可大大提高贯通精度,实际贯通精度明显高于《煤矿测量规程》规定标准。实践证明,“四架法”测量速度快、精度高,特别是三角高程测量闭合精度达到三等、接近二等水准测量要求的精度。为同行业从业者提供参考依据或后续规程修订提供基础支撑,具有较高的推广应用价值。

Over the years,the coal mine surveying technology has not changed much,and the Coal Mine Surveying Regulations has not been revised for a long time,which can no longer meet the current needs of mine survey.Systematically summarized six large-scale penetration engineering examples in the past 12 years in Zhangshuanglou Coal Mine.With the use of current precision instruments,the"four frame method"measurement process can greatly improve the penetration accuracy.The actual penetration accuracy was significantly higher than the standard specified in the Coal Mine Surveying Regulations.Practice has proved that the"four frame method"has high measurement speed and accuracy,especially the closure accuracy of trigonometric leveling can reach the third class and close to the accuracy required by the second class levelling.Providing reference basis or basic support for subsequent regulations revision for practitioners in the same industry has high promotion and application value.
