Abstract

Abstract: The southeastern of Yunnan metallogenic belt is an area with many large- super large deposits in the Metallogenic Province of South in China. The mineral deposits in the area are densely distributed and the geological structure is complex. This article studies the joints (cracks) of the super large bed in the Bainiu factory in this area, a total of 21 joint observation points, 685 groups of occurrence structural surfaces were observed, and uses Dips software to analyze the joints (fissures) in the mining area. It is concluded that there are three periods of tectonic stress in the mining area, which are closely related to the mineralization, there are North North West-South South East, North East-South West, and South-North.
