Paper Title:
Analysis of Ground Fissures Induced by Underground Mining in a Metal Mine
  Abstract

Jinchuan nickel mine is the largest cut-and fill mining mine in China. After keep successive mining for nearly twenty years, it appeared serious ground fissures. A major thrust of this paper is to discuss the distribution features, deformation regularities, development tendency and formation mechanisms of ground fissures based on long-term subsidence monitoring and investigation. The results showed that large-scale ground subsidence basin has been developed in the mine area, and the ground fissures mainly scattered in the tensile zone of the subsidence basin. Besides, ground fissures have the features of compressive shear or tensile mechanical properties and zonary pattern. Unfortunately, with the mining scale keep expanding, both the quantity and width of the ground fissures increased rapidly. This will be unfavourable to safety of mining and engineering facilities. Therefore, strengthened monitoring and prevention works are essentially important to the similar mines which designed with cut-and-fill mining method.
