煤矿巷道贯通测量精度及增强策略研究
|
摘要
本文将山西兴盛鸿发煤业有限公司煤矿主井、风井的贯通测量作为研究对象,设计了地面控制测量、地面水准测量、井下陀螺定向与联系测量及井下导向测量方案。通过实施得出高程闭合差为78mm,方位角闭合差为26″,坐标闭合差均小于30mm,均满足了煤矿贯通测量的规定,对于类似工程的贯通测量有一定的参考意义。
This paper takes the survey of the main well and wind well of Shanxi Xingshenghong Coal Industry Co., Ltd. as the research object, designs the ground control measurement, ground level measurement, downhole gyro orientation and connection measurement and downhole orientation measurement scheme, and adopts the implementation scheme. The resulting elevation closure difference is 78 mm, azimuth closure difference is 26″, and the coordinate closure difference is less than 30 mm. All of them meet the requirements of coal mine penetration measurement, and have certain reference significance for the penetration measurement of similar projects.
