Mining environment regeneration and induced caving technology in mine engineering

Abstract

Considering the understanding on the idea of environmental protection and sustainable development in recent years, limitation of traditional concepts of people was beoked to realize the changes and innovation for the thinking of mining technology. The science conception of mining environment regeneration is put forward to accord with the situation and needs at present. The meaning of this conception that the geological environment of mineral deposit is regarded as structure environment and boundary condition. By using special technical ways of mining and geotechnical engineering, we can improve mining conditions, reframe mining space and satisfy the needs of security and high efficiency of exploitation. Based on continuous mining technology, induced caving technology adopts artificial advance disturbance to induce roof failure and build a safe workspace. It can avoid the great disaster as well as guarantee the trouble-free execution of continuous mining technology. Moreover, this technology decreases the negative domino effect of mining action on environment which accord with the essence of mining environment regeneration. In addition, new technology develops the passive modification into the active regeneration of mining environment. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
