摘要矿山测量是开发矿业过程中不可或缺的一种重要基础技术工作。矿山联系测量工作是矿井建设工程的必要前提,井上井下使用相同的坐标系统,使井上井下坐标形成联系,便于建设和生产。但是在实际测量中,由于井深,地下渗水,地下风力等因素的不同,最后得出的结果和实际结果误差较大,误差较大的条件下可能会有工程隐患,高精度的联系测量可以有效的避免矿山的岩层移动,地表塌陷,开裂,透水等灾害,同时也是矿山其他工程技术工作的保障依据,提高测量精度需要对联系测量方案进行优化。依据几何定向,在井下加陀螺边,提高测量精度。在比较不加陀螺边的方案,分析两者测量的误差,得出更优方案。39518 毕业论文关键词: 矿山测量,一井定向,误差分析,方案优化
Abstract
Mine surveying is indispensable in the process of development of mining is an important basic technical work. Mine contact measurement is the necessary premise of mine construction project, use the same coordinate system, inoue underground to form inoue underground coordinate contact, convenient for construction and production. But in actual measurement, the well depth, the underground water seepage, underground factors such as wind, finally the results and the actual result error is larger, there may be a project under the condition of hidden trouble of error, high precision of contact measurement can effectively avoid the mining strata movement and surface subsidence, craze, floods and other disasters, as well as other mines on the basis of security engineering work as high as possible to improve measurement precision need to optimize the contact measurement scheme. Depending on the geometry directional, at the edge of the downhole and gyro, improve the accuracy of measurement. Scheme on the edge of comparison without gyro, the error of measurement are analyzed, concluded that a more optimal solution.
Key words(加粗): Mine surveying, a directional well, the error analysis, scheme optimization
