摘　　要：根据牛山煤矿9号煤层的开拓方案,回风立井与主斜井需要进行贯通,在贯通前需要对测量作业进行设计。结合有关规程规范从控制点建立、立井联系测量、导线施测、陀螺定向测量、施工放样等方面阐述并提出有效的工作方案,并对该方案进行误差预计。在回风立井井下起始边及内侧加测2条陀螺定向边,不仅能减小测角工作量、提高工作效率,而且能提高全站仪导线测量精度。结果表明,该工作方案合理可行,不仅为井下贯通施工提供可行的工作方法,也能保证巷道的顺利贯通。According to the development plan of No.9 Coal Seam under the shaft of Niushan Coal Mine,the main inclined shaft and the air return shaft need to be holing through,and the survey operation is required to be designed before the connection.The author puts forward effective scheme for the setup of control points,shaft connection survey,traverse survey,gyro orientation survey and construction layout survey in combination with relevant regulations and specifications,and predicts the error of the scheme.Two gyro orientation edges are additionally measured at the starting edge and inner side of the return air shaft,which not only reduces the workload of angle measurement and improves work efficiency,but also improves the accuracy of total station traverse measurement.The results shows that the scheme is reasonable and applicable,which provides a feasible working method for the roadway connection construction and can ensure the smooth penetration of the roadway.
