Mechanism and Forecast of the Ground Subsidence in Daxin Lead-Zinc Mine in Guangxi

Abstract

Abstract: Ground subsidence is a geological disaster due to various complex causes.Underground mining is one of the causes and the process of ground subsidence caused by underground mining is a complex systematical issue.In view of the real ground subsidence conditions at Daxing Lead-zinc Mine in Guangxi, the research and forecast of ground subsidence mechanism was carried out by means of site investigation, surface displacement monitoring and grey model.It is of important practical significance to the study of the ground subsidence development trend caused by metal mine production and to avoiding its danger.

Key words: Lead-zinc mine, Ground subsidence, Forecast, Grey model, Underground mining
