千米深井巷道严重形变测量控制技术

Survey control technology for serious roadway deformation in 1000 meter's deep shaft

山东唐口煤矿为千米深井开拓开采,矿井地压大、巷道变形严重,井下测量控制点处于移动中。为做到安全生产,采用井下陀螺定向技术检测井下测量控制点稳定性的方法,利用巷道变形FLAC3D数值模拟及地应变计算,确定了井下测量控制点埋设的最佳位置为巷道"拱顶两侧"位置,并开发了千米深井井下测量数据管理信息系统及矿图自动更新软件。

The Tangkou coal mine in Shandong is developing mining of 1000 meter＇s deep shaft.The mine has large pressure,with serious roadway deformation,and the underground survey control points are in moving.In order to ensure production safety,the method of testing stability of underground survey control point in underground directional gyro technology are used,combing FLAC^3D numerical simulation and strain calculation.The best laying location for underground survey control point is confirmed,that is ＂both sides of the vault＂,and the surveying data management information system and Mine Map software are developed.
