Qinshihuang Mausoleum is the largest one of Emperor Mausoleums in our country. According to the historical records, there are great deals of treasures in the underground palace of Qinshihuang Mausoleum. One of 863 national projects used remote sensing technology and geophysical technology to detect Qinshihuang Mausoleum, and revealed the secrets about the position and arrangements of underground of Qinshihuang Mausoleum. The proposal that the further detection to see what in the underground palace should be done with drilling or tunneling technology companied with image technology, such as snake patterned robots, to keep the original structural and environmental facts from being destroyed is put forwards. New thoughts of using drilling and tunneling method for archaeological survey are offered.
