2 days ago Two coal companies planning to develop mines in Alberta's Rocky Mountains say they hope to move forward despite new regulatory and political roadblocks. We feel that our mine plan that we are going to present is unique to the situation we're in, said Peter Doyle, head of Montem Resources, which hopes to build a new open-pit mine in southern Alberta on a previously worked deposit.
33 In mine designing and production planning it is very important to have information about ore body quality and resource tonnage estimation in each level (elevation) of mining. Therefore you can predict the Run of Mine quantity and quality for each bench (in open pit mining).
Jul 06, 2020 Benga Mining Limited, a wholly-owned subsidiary of Riversdale Resources Limited, is proposing to build an open-pit metallurgical coal mine approximately seven kilometers north of Blair . It would produce a maximum of 4.5-million tonnes of coal per year over its.
Jul 30, 2020 Open-pit coal mines require complete de-forestation and removal of all vegetation, small creeks, and intermittent streams on-site. This means that all of that habitat for aquatic species and terrestrial wildlife must be removed until the mining company closes the operation— and hopefully—reclaims and restores the land.
Jan 18, 2021 A 1976 policy brought in by Peter Lougheed's government laid out how and where coal development could go ahead, forbade open-pit mines over a large area and banned any mining at all in the most sensitive spots.
Feb 01, 2021 The Alberta government’s decision, in June, to rescind the 1976 coal policy has opened up 420,000 hectares of land classified as Category 2, a designation that had prohibited open-pit coal mining. Much of the area is already covered by coal leases, meaning companies can begin coal exploration and apply to build new open-pit mines.
Dec 28, 2020 Kiselevsk is a city of 87,000 inhabitants in the Kemerovo region and counts as many as 9 active open pit coal mines in the city area, run by several different mining companies. Coal production accounts for 70 - 75 of overall economic production of the city.
