paringa logo rdsMCLEAN COUNTY, Ky. (3/26/19) — Paringa Resources officials yesterday said the initial ramp up phase, underground mucking and transportation of run of mine material to the surface has to-date been undertaken using underground loaders, rather than a permanent slope conveyor. RoM volumes being brought to the surface are lower than expected due to a Mine Safety and Health Administration directive last week limiting operations to one loader.

Consequently, the company has decided to install the slope conveyor sooner than originally planned. The slope conveyor has the capacity (nameplate) to transport up to 2,000 tons of RoM material per hour from the slope bottom and will enable the Company to further improve the planned ramp up of production from the mine. First coal sales are now expected to be in the week of April 22 instead of this week.

Although the first shipment of coal will be delayed, the establishment of the permanent ventilation system and operations using the mine slope conveyor will allow the company to commence a typical underground room and pillar mining sequence, significantly increasing mining advance rates and eliminating the haulage bottleneck currently limiting the mine's production ramp-up.

Connection to the intake ventilation shaft will be made this week allowing the ventilation update necessary to commission the 400-hp main mine fan. The connection to the intake shaft and commissioning the mine fan allows the establishment of the permanent ventilation system.

The company issued the following synopsis:

• Underground mining progressing well, with the coal face and roof support operations performing as expected. The mine development contractor has demobilised.
• Initial RoM coal volumes being brought to the surface are lower than forecast due to a new MSHA directive limiting operations to one loader.
• Consequently, the company has decided to bring forward installation of the slope conveyor.
• Due to the installation of the slope conveyor first coal sales are now expected to be in the week of April 22.
• Despite delaying first coal sales, bringing forward installation of the slope conveyor will eliminate the haulage bottleneck currently limiting the mine's production ramp-up.
• Underground connection to the intake ventilation shaft will be made this week, allowing the establishment of the permanent ventilation system.
