忻州窑矿中央回风上山贯通测量精度分析 摘要 井下贯通测量一直是矿山测量工作的一项非常重要的技术工作，井下巷道贯通如何提高其精度，确保其准确、安全顺利贯通，对于测量工程技术提出了较高的要求，同时也关系到矿井的生产建设，经济效益和安全。因此，在巷道贯通任务书下达后，首先应编制贯通测量设计书，对贯通工程所要达到的精度要求和所采用的测量方案进行贯通前的误差预计。 本文通过对忻州窑矿中央回风上山贯通工程方案的分析，对影响巷道贯通的地面控制导线精度，立井定向，矿井联系测量和井下导线测量等进行精度分析和误差预计，讨论了提高测量精度的可行性方法。为以后同等条件下的贯通提供参考和借鉴。 关键词：贯通测量，误差预计，精度分析 The accuracy analysis of tunnel break survey up crossing the central air return of xinzhouyao coal mine ABSTRACT Tunnel break survey underground mine has been always a very important technical work in the coal mine survey.For the survey project, the problem that how to enhancement of its accuracy, ensure accurate, safe and smooth through, made for the measurement of higher engineering requirements, but also related to Mine production and construction, economic, and security. Therefore, the mission statement issued through the tunnel, the first design document should be prepared through measurement on linking projects to achieve the precision and the measurement used in the program through before the error is expected. Based on the central air return Xinzhouyao mining engineering program through the analysis of the mountains, on the impact of tunnel through the ground control network, directional gyro shaft orientation and processing side, mine surveying and underground cable connection for the accuracy of measurement and error estimates discussed the feasibility of methods to improve the measurement accuracy. Under the same conditions as the link that provide reference.
