At large-scale ore mines, to optimize costs as well as mining plans, it is necessary to have a topographic map to design mining routes and arrange drill holes for exploration… Therefore, topographic survey of ore mine is very necessary. Hop Nhat Bach Viet Co., Ltd performed Topographic survey of ore mine in Central Laos. Let’s find out following post.

Purpose of topographic survey of ore mine in Laos

Topographic survey provided large scale topographic maps for the following purposes:

  1. Providing topographic plan for planning and designing mining construction plan: mining area, transportation, factory area…
  2. Providing a topographic plan to design a reserve exploration route
  3. Calculating mining reserves.
  4. …

Method of topographic survey of ore mine in Laos

The topography of the survey area is quite difficult, there is no 3G signal in this area. Therefore, the contractor used the topographic survey method using UAV combined with DGPS. The contractor uses GNSS static receivers and set coordinate control landmark. After adjusting, the coordinates of the control point in the topographic survey area can be calculated.

Use a base station to transmit to rovers to measure in detail.

Besides, using UAV phantom 4 RTK device to do 3D topographic survey of the mine in Laos. To improve the accuracy of topographic survey results by UAVs in Laos, the contractor used GCP points placed 300-500m apart throughout the project.
