金庄煤业副斜井三头并进贯通控制测量

摘要

The method of tunneling from three directions in one roadway is applied to the auxiliary slope cut -through in Jinzhuang Coal Company;meanwhile,the different measurement techniques including GPS satellite positioning technology,total station mine orientation technology,total station triangle elevation,and three support methods are used in the process.Results show that both the actual deviation and the polygon misclosure have met the requirements of Coal Measurement Regulations,realizing the cut -through accurately and rapidly.%金庄煤业副斜井贯通采用了相向贯通和追随贯通相结合的“三头并进”方式，并结合使用了 GPS 卫星定位技术、陀螺全站仪矿井定向技术、井下全站仪三角高程与“三架法”相结合的方法进行了贯通测量。结果表明，贯通的实际偏差及各项闭合差均满足《煤矿测量规程》的技术要求，实现了巷道的快速、准确贯通。
