Arctic Canadian Diamond Firm and IHC Mining report that they’ve reached the following essential milestone within the growth of the underwater distant mining (URM) system for the extraction of diamond-bearing kimberlite ore from deep open pits on the Ekati Diamond Mine within the Northwest Territories of Canada.
Arctic Canadian awarded IHC Mining with a contract to construct and ship an Underwater Mining Crawler for the URM system, a contract that follows the primary milestone of the Launch and Restoration Platform being awarded by Arctic Canadian for the URM system, earlier this yr. The platform is scheduled for supply by the top of 2022.
Arctic Canadian and IHC Mining began their cooperation in 2018, to collectively develop a mining answer. The place to begin for the event of the underwater distant mining system, was to economically extract kimberlite from marginal kimberlite pipes and from deep extents of accomplished open pits.
An essential focus is to develop a mining answer that may have a a lot decrease environmental affect than typical mining strategies. Because the URM crawler is simply mining the kimberlite ore and minimal waste, it considerably reduces the mine’s footprint. The URM answer may enable the Ekati Diamond Mine to increase its lifetime by no less than 10 years.
The underwater mining crawler is a distant operated steady mining machine, geared up with the most recent underwater management and positioning tools. The ore is straight excavated with a drum cutter in small layers and eliminates the necessity for blasting explosives.
From the crawler the ore is pumped to the floor of the flooded pit by way of a vertical pipeline system to the Launch and Restoration Platform, from the place the ore is transported additional to a dewatering plant. The crawler system is able to working at a water depth of as much as 400m.
The mining crawler might be constructed at Royal IHC’s premises within the UK and delivered to Arctic Canadian late 2023. It should then be trialled within the Lynx pit in the summertime of 2024, along with the opposite parts of the URM answer.
The objective would be the extraction of roughly 150,000 tonnes of Lynx kimberlite ore.
