Rolatube CFRP Masts in Mining: Camera Coverage Without Civil Works in Open-Pit

The mobile coverage problem in open-pit mining

A large Peruvian open pit — Antamina, Las Bambas, Cerro Verde — advances between 15 and 40 meters per month in the mining direction. Each advance cycle displaces the optimal location of perimeter surveillance cameras, Rajant Kinetic Mesh network nodes, and fleet dispatch system antennas. With fixed infrastructure — concrete towers, steel poles — this advance requires repositioning civil works costing USD 8,000-25,000 per point and taking weeks on the calendar.

The practical result is that camera and network coverage becomes systematically outdated relative to the active face. Blind spots in the pit increase with each blast. Rajant nodes fall outside the optimal range of autonomous vehicles. HSE supervision loses visibility exactly in the highest-activity zones.

Rolatube: tactical elevation that moves with the mine

Rolatube CFRP masts allow installing a camera or antenna point on unprepared terrain in under 10 minutes, with a single operator, without cranes, specialized tools, or civil ground anchoring. The autonomous base system includes ballast weights or threaded steel stakes for soft ground.

Use case 1: Dynamic PTZ coverage of the active mining face

Standard open-pit operation includes active zones that shift position with each blast. DS 023-2017-EM (Peru's Mining Occupational Safety Regulation) requires visual supervision of exclusion zones during blasting and a 500 m safety radius near the pit edge.

With Rolatube QDM-9 masts, the HSE team can install an IP65 PTZ camera at any active pit point in 5 minutes, transmit video through the local Rajant Kinetic Mesh node, and retrieve equipment before the next blast. The full install-record-retrieve cycle requires no additional personnel or civil planning.

Use case 2: Kinetic Mesh coverage extension without civil works

Rajant Kinetic Mesh nodes in a large open pit need placement at 300-500 m intervals to guarantee FMS throughput (Wenco, Modular Mining, Jigsaw). When the face advances faster than civil works planning for new towers, dispatch throughput drops and autonomous haul trucks miss cycle updates.

The Rolatube QDM-9 allows installing a Rajant BreadCrumb Cardinal node at any pit position as a provisional extension node. The Cardinal weighs 850 g and operates via PoE; the power cable runs through the mast's integrated channel. The assembly installs in under 15 minutes and can be relocated as the face advances.

Regulatory compliance

DS 023-2017-EM (Peru) requires mining companies to maintain reliable communications in all work zones. The Rolatube + Rajant Kinetic Mesh combination meets the network redundancy, continuous coverage, and emergency communications availability requirements in articles 200-225 of the regulation.
