Kaya Düşmesine Karşı Koruma Bariyerleri

Following the major landslide that occurred in February 2024 in the heap leach area of the Çöpler Gold Mine, located in the İliç district of Erzincan, a pressurized pipeline was installed to safely discharge contaminated water from the site. This initiative represents the second stage of a rockfall protection project for the discharge pipeline, which initially included the installation of 770 m² of RB 1000 rockfall barriers and 6,000 m² of SteelGrid HR50 mesh during the first phase in 2024. However, due to its location, the pipeline remained exposed to a high risk of rockfalls. The disrupted slopes and irregular accumulation of debris caused by the landslide created conditions conducive to rock detachment and debris flows, posing significant threats to both the pipeline and nearby infrastructure. To mitigate these risks, the first phase of protective measures was implemented in 2024. Critical slopes were stabilized using passive SteelGrid HR50 systems, and a rockfall barrier—measuring 220. 0 meters in length and 3. 50 meters in height, with an energy absorption capacity of 1,000 kJ—was constructed. All the rockfall barrier materials are CE marked and the barriers are certified according to the EAD 340059-00-0106 (ex ETAG027). While these interventions proved effective in the short term, ongoing site monitoring revealed the need for additional measures to ensure long-term slope stability and enable continuous geotechnical observation of the area.

The Ziordia quarry has an orography formed by limestone rock, with steep slopes as a result of quarrying, and potentially unstable large blocks. The company CRS Ingeniería contacted Bianchini Ingeniero to analyse the situation and possible solutions, and subsequently the company Inaccés Geotècnica Vertical also intervened. One of the main risks was the blocks that could fall from a 40-metre-high, 15-metre-wide mochón, located on one of the quarry's usual passageways. This represented a potential risk for the installations and the workers themselves. Therefore, a series of actions were carried out to stabilise these blocks and protect the area.
