摘　　要：介绍了广东高要河台金矿永久性与临时性井巷支护技术,在矿山生产过程中,常用巷道因岩体结构节理弱面存在,再加上爆破振动与空区地压等原因而开裂或破坏,巷道维修方法多种多样,要以施工质量和支护速度为第一要素,以求在矿山生产时间内作到安全为目的。主要运输与通风平巷支护率为7.24%。This paper introduces permanent and temporary timbering and maintenance technology of Hetai Gold Mine. During production process, commonly used laneways are likely to be cracked or damaged by reasons of existence of joint weaker plane of rock body, plus vibration caused by demolish and ground pressure of hollow areas, etc. The ways of shaft-lane maintenance are various; construction workmanship and rapidity of timbering are of most importance, so as to guarantee safe production. The timbering ratio of main transport and ventilative laneways is 7.24%, which indicates preferable robustness of rock.
