Abstract: Industrial and mining heritages are the concept of conbining the industrial heritage with geological heritage，which is not a new concept nowadays． With the exhaustion of the mining resources， the upgrading and transformation of the mining industry，more and more mining legacies have been abandoned，hence the concept of the industrial and mining heritages gradually moves into public view． In order to build up a new protection system for industrial heritages， this article utilized the theory of adaptive reuse and started from the angle of architecture，six principles of the industrial and mining heritages protection were put forward: static and dynamic combination of principle， style and feature maintenance principle， function-update principle，diverse technology principle， old and new identification principle， step-by-step implementation principle． Besides， six ways of protection were proposed: in-situ update protection，migrationprotection，embeddedprotection，enclosureprotection，ruinedprotection and factor protection．
