摘　　要：传统的测斜仪多为不防磁的罗盘测斜仪,在钻孔测斜时需要拔出钻杆进行裸孔测量,该种测斜方式有不防磁、精度差、测量劳动强度大、易出孔内事故等缺点。本文将介绍一种新的测斜仪器和测量装置,采用无线光纤陀螺测斜仪和计米器的组合,利用钻机自带的打捞钢绳及提升系统,在不拔钻杆的情况下,实现了对某铁多金属矿钻孔轨迹的一次性准确测量。Traditional inclinometers are mostly non-magnetic-proof compass inclinometers.When drilling inclination,you need to pull out the drill pipe for bare-hole measurement.This type of inclinometer has the advantages of non-magnetic-proof,poor accuracy,high labor intensity and easy measurement.Disadvantages such as accidents in the hole.This article will introduce a new inclinometer and measuring method,using the combination of wireless fiber optic gyro inclinometer and meter counter,using the fishing rope and lifting system that comes with the drilling rig,to achieve this without pulling out the drill pipe One-time accurate measurement of the trajectory of a certain iron polymetallic mine.
