摘　　要：介绍了金川矿区自20世纪70年代以来的监测技术的发展和应用,包括地应力测量、收敛变形观测、围岩深部变形观测、地表沉降监测等方面.其监测手段主要有以下3种:(1)收敛仪、测杆、钢尺和激光测距仪等的直接观测法;(2)多点位移计、伸长仪、声发射仪等设备的深部围岩观测手段;(3)光纤光栅信息融合技术.这些监测技术已经为并将要为金川矿区的安全生产和岩石力学研究发挥重要作用.This paper has introduced the application and development of monitoring technologies in Jinchuan Mine since the 1970s, which include In-situ stress, convergence deformation, deep surrounding reck deformation, ground settlement, and so on. These monitoring technologies are as follows： （1） The direet observation with convergence indicator, rod, steel rule and laser range finder; （2） The deep surrounding rock observation means with multi-point extensometer, extensometer, acoustic emission instrument; and （3） The information fusion technology with fiber and grating. These monitoring technologies have been or will be playing an important role for safety produetion and rock mechanics in Jinchuan Mine.
