Quintette Coal Project

British Columbia, Canada

Successful MAPA application for metallurgical coal mine

 
The Quintette mine was a 5 Mt/year steelmaking coal mine located in northeast British Columbia, 20 km south of Tumbler Ridge. The mine was in operation between 1982 and 2000. KCB designed and performed construction management for the Shikano North pervious rockfill tailings dam at the mine. The dam was built to create the Shikano North In-Pit Tailings Impoundment, which provided storage for fine coal tailings produced by the coal washing plant. The tailings dam was designed as a pervious structure to continuously decant the tailings pond by seepage through the dam. This eliminated the need for a $2M reclaim water pumping system to transfer the tailings water from the impoundment.

Following mine closure, the project was reassessed in 2009, and a feasibility study was completed in 2012 to re-open the mine. It is currently under care and maintenance due to unfavourable market conditions. KCB was responsible for the design of the tailings storage facility and waste rock dumps, and a water management system, including water quality mitigation strategies, water balance and hydrogeology studies. KCB supported the feasibility study and Mines Act Permit Amendment (MAPA) application in 2012 and 2013.
