Project Overview
Project Overview and Location
 
HD Mining International Ltd. (HD Mining) proposes to develop Murray River Coal Project (Project) as a 6 million tonne per year (6 Mtpa) underground metallurgical coal mine. The Project is located 12.5 km southwest of the town of Tumbler Ridge, British Columbia (BC; Figure 1). The coordinates are E 112°54'03"-121°18'07", N 54°56'59"-55°09'59".

The Project will produce approximately 4.5 million tonnes of metallurgical coal product, and 6 million tonnes of ROM coal per year over 31 years. A 5-year construction phase is currently planned, and the mine will operate for 25 years. The closure phase is approximately three years and HD Mining has planned for a 6-year post-closure monitoring program (i.e., following the closure phase). The monitoring results will be used to assess reclamation success and whether certain aspects of the post-closure monitoring program can be shortened or extended.

 

Coal will be mined using long-wall mining, which is designed to maximize extraction rates while maintaining worker safety and there  are five coal seams that will be targeted for mining: D, E, F, G/I, and J (depth increases  alphabetically). The underground area has been divided into four large coal Blocks, with each Block  consisting of 10 to 30 panels in all levels of coal seams. The current underground mine layout  includes a total of 84 panels. Where multiple seams are planned to be mined vertically, mining will  begin at the shallowest seam (e.g., D Seam), and work downwards. The majority of production is  planned in the F and J seams. Exact locations of the coal seams and key project infrastructure, such as the decline site, are provided in Figure 2. For further insights into our project infrastructure, please refer to the dropdown section below, which offers comprehensive details on each component.

Project Infrastructure

  • underground mine;
  • decline site;
  • shaft site;
  • coal processing site; and,
  • secondary shaft site.

Major Project Components

  • waste rock storage facilities;
  • overburden and soil storage areas;
  • explosive and soil storage areas;
  • coal rejects storage areas;
  • coal handling and preparation facilities;
  • coal conveyor; and,
  • rail load-out.

Key Benefits of Underground Mining

  • Underground mining will produce limited waste rock, and the mine will have a small surface footprint compared to an open pit mine of equivalent production rate;
  • Project infrastructure and disturbance will be limited to areas of low elevations (outside of core caribou habitat) and in areas of pre-existing disturbance;
  • Roads and utilities infrastructure (e.g., power, natural gas, rail) already exist and minimal expansion of this infrastructure will be required to support the Project; and,
  • Dewatering of flotation tailings will allow co-mingling of coarse and fine coal rejects in a single facility so there will be no subaqueous tailings storage, reducing closure liability.
