上坪深部开拓副斜井工程贯通设计与方案实施

The Through Design and Practice of Auxiliary Slope-shaft Project for Deep Digging in Shangping

编制贯通设计的主要任务是选择合理的测量方案和测量方法,以保证巷道正确贯通。结合上坪矿区自身的实际,选择适当的贯通测量方案和测量方法,并对其误差进行了误差估算。在此基础上,介绍了其深部开拓副斜井贯通工程的测量实践及其精度分析。采用经多次检测无误、标志稳固的429中段副斜井进路附近的点N2坐标及其标高、边N1-N2的方向作为起始数据,进行坐标、方位、高程传递。于2005年9月开始施工,按其设计的测量方案及测量方法精心实施测量,工程于2006年元月顺利贯通。不仅保证了贯通工程的测量精度,而且经实测,本次贯通测量的实际偏差低于限差,与预计误差相近。

The main task of making the through design is to select a reasonable measure proposal and method to ensure the roadway right through.According to the practice of Shangping mining area,an appropriate measure approach is selected to make error calculation and assessment in advance.Based on this,the measuring practice and its accuracy analysis for deep extension of new auxiliary slope-shaft in Shangping mine are mainly introduced.Taking correct and stable coordinates and elevation of the starting point N2 and the azimuth of the starting side N1-N2 as original data,the traverse measurement of coordinate,azimuth and elevation is carried out.The project was put into practice in September,2005 and completed smoothly in 2006.The through engineering not only guaranteed the diagraph accuracy of measurement,but also ensured that the actual deviation of the through engineering was lower than the limited error and near to the anticipating error by the practical measure.
