| Along with developing of mining, A large number of shallow minerals are mined out in the Earth. Mining for minerals from shallow place to deep place, survey technology of deep mine s construction project has decisive effect to opening deep minerals during shallow minerals are being mined and mining under 1 km.This paper unite surveys works in Dong gua shan mines construction under 1 km place researching four key technology in mine s survey, they are construction survey technology in km deep mine, km deep mine s connected survey technology, km deep level survey technology of longer distances link up in many heads opening and basic control survey technology, km mine s extension when the production must go on accurate fixed position survey technology, and all obtained success.This paper has some value for surveying works of similar engineering project. |
