Abstract:

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; construct ion 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.

Key words: gold deposits, deposit exploitation, shaft-lane engineering, timbering and maintenance
