In actual measurement, adopting diversified information and surveying and mapping technology is conducive to further improve the quality and precision of measurement. In this paper, the role of the impact on mine survey is introduced. Moreover, the present situation of using geographic information, surveying and mapping technology and its future development prospect are discussed.展开更多

While mining the mine, it is necessary to fully do the mine survey work, if the work is not put in place before mining, then after entering the infrastructure stage, the mine safety production will be greatly negatively affected. Therefore, in order to promote the further improvement of mining efficiency and control the incidence of accidents, it is necessary to do a good job of preliminary measurement. However, in terms of the current situation of China's mine survey work, there are still many problems, only to deal with these legacy problems in place, the mine survey work can be carried out smoothly, under the premise of ensuring the quality of the development, but also to provide adequate protection for the safety of the relevant personnel.展开更多
