Abstract

The Tonglushan ancient copper mine relics in Daye of Hubei province is the ancient copper mine relics in China with the most complete preservation, the earliest excavation time, the highest smelting level and of the largest scale. However, deformation and cracking recently occurred in the copper mineral relics. According to the engineering geological conditions and surrounding environment of ancient mine relics, the main factors of slope deformation as well as the deformation were analyzed. In view of the deformation characteristics of ancient copper mines, the deep sliding force monitoring system was adopted to continuously monitor the slope stability of relics. According to the monitoring curve, the sliding force of No. 6-2 monitoring point presented a sudden drop on 13th February through field survey; the reason was that the local collapse of goad occurred around the No. 6-2 monitoring anchor cable, leading to the reduction of shearing force supplied by unstable body on the cable. Through drilling and geophysical exploration, the distribution of goafs around the relics were probed, revealing that the old goafs beneath the relics constituted the basic inducing mechanism of relics deformation, while the method of filling and grouting were proposed to control the goafs.
