For mines with complex natural terrain conditions, especially for open pit mines with poor slope stability; traditional surveying and mapping techniques are difficult to accurately map engineering quantities and have certain safety hazards. Based on the actual production, this paper systematically studies the key technology of multi-view image matching point cloud in the calculation of mining area engineering quantity, and verifies the feasibility and accuracy of it, and compares it with GPS-RTK, traditional aerial survey and other data acquisition technologies. Comparative analysis shows that multi-view image matching point cloud technology has certain advantages in terms of time, accuracy, cost and security risks.  1,  a*
