SANTIAGO (Reuters) -Chile's mining regulator Sernageomin has added requirements for Codelco to restart areas affected by a deadly collapse at its El Teniente copper mine in July, according to a document seen by Reuters on Monday.
The regulator will now require a follow-up and monitoring plan for the stability and safety of mining operations across all underground deposits of Codelco's El Teniente mine, according to a Sernageomin document.
In a statement this weekend, Codelco said it
had received approval from Sernageomin to restart its Andes Norte and Diamante sections of El Teniente, but the document detailing the authorization obtained by Reuters on Monday revealed the increased requirements for sectors still shuttered by the collapse.
Sernageomin had already requested analysis of potential causes and control measures report to prevent new incidents; as well as a mine recovery and repair plan; and a technical report assessing existing fortification systems with proposals for improvement.
Codelco, the world's largest copper producer, cut its copper forecast for this year due to the impact of the accident, which killed six workers.
The collapse mainly affected the new Andesita development, but Andes Norte, which had begun extraction, and Diamante were also halted as part of the investigation.
