In an open-pit mine or quarry, a drone survey refers to the use of a drone (or UAV – unmanned aerial vehicle) equipped with a downward-facing RGB camera to capture images of a site from different vantage points. Out of these images, a photogrammetry software can recreate geo-referenced 3D maps, contour lines digital terrain models or digital surface models of the

In general sublevel stoping is a high production, yet low-cost method. It is a very popular method chosen when open pit mining activities are no longer economical and mines move to underground operations. The key to cost minimization when using this method is mechanization.

Sep 25, 2014· The Office was never open anymore and it was frustrating to our tenants. We also requested he consider putting in a drop box so tenant’s could pay their rent this way. He then posted a notice on the office door stating all rent was to be paid through the mail by check.
