Abstract: The design concepts and construction results of 12 shallowburied tunnels constructed by mining method in China in the past decade are discussed and analyzed. New trends of shallowcover mining method are summarized, which includes: 1) strengthening the assistant construction methods and simplifying the main construction method; 2) improving the mechanization level, the automation level and the digitization level so as to minimize the labor requirement; 3) bringing the risks of the assistant construction methods under effective control; 4) minimizing the cost of the assistant construction methods. 
