摘　　要：巷道收敛量测对监视矿山巷道稳定性、保障矿山安全生产起着重要的作用。本文阐述了用于巷道收敛测量的ＷＲＭ－ ３ 型丝尺两用收敛计的结构组成和性能以及操作使用方法。通过现场实例测试与分析，揭示了巷道收敛（ 变形） 随着开挖时间推移的变化规律。The measurement of drift convergency plays a important role in monitoring the stability of drifts and chambers in mines and ensuring the safety of mine's production.This paper expounded the structure,the performance and the operational method of Model WRM-3 wire-recording meter —— a dual purpose convergency meter for the measurement of drift convergency,and on the basis of site test and case analysis,revealed the law of the variation of drift convergency (deformation)with the lapse of excavation time.
