摘要
本文以北煤公司冠山矿一、三井-540 m水平岩巷巷道贯通为例,在比例尺为1∶5 000贯通平面图上进行方案设计,根据所使用的仪器,应用不同的方法,分别制定两套不同的设计方案.然后对两套方案进行误差预计和工程预算,将结果进行比较,选择既满足精度要求又经济、高效的测量方案作为最后的误差预计方案.最后求出已选方案陀螺定向边和贯通相遇点的最佳位置及贯通允许区间.
Taking lhe tunnel between Guanshan first mine and third mine of Northern Coal Group as an example, the plan design was car,＇ted out with the scale of 1：5 000. Different methods were adopted according to different instrument used, and two sets of different design proposals were formulated. Then the erroneous estimation and the project budget were conducted for the two sets of plans, with their cslimatiul results compared. The economical and highly efiective survey plan that satisfies the precision request was chosen as the one tot error estimation. Finally, Ihe calcnlation was done for the most optimum position of the gyrocompassing side, the transfixion engagement puiut and the permission sector of through survey.
