Appendix Gs Air Quality and Greenhouse Gas ... - Peabody Energy

2 Project DescriptionThe project information has changed since the original ASK air quality and greenhouse gas report5001R02V03. This section presents the latest details.2.1 Project DescriptionThe proposed bulk sample maximum Run of Mine (ROM) is 5.25 Mt per annum of product coal.The life of the mine is proposed to be mined over 16 years.Mining and processing plant will operate 7 day a week, 24 hours a day. Mining will be open pitusing conventional truck and shovel excavation methodology, with potential for future undergroundactivities. The proposed Project infrastructure and pit layout is shown in Figure A.1 to A.3 inAppendix A.ROM will be hauled to the processing plant via haul roads from the pits. Waste material will bestacked on out of pit waste dumps adjacent to the pits until sufficient room becomes available inthe pit at which stage waste will be placed in mined out pit areas. Excavators will load materialfrom the pits into dump trucks for transport to the stockpile. Front end loaders will load thecrushed ROM coal into the haul trucks. Road transport trucks will enter the site to load productcoal at the coal handling process plant (CHPP) and travel along a haul road between the CHPP andMoorvale Mine for loading onto trains. Associated pieces of equipment such as drills will also beoperating at the face. Service vehicles and water trucks will operate on the haul roads. All thesesources are included in the model.The equipment utilisation is included in Table 2.1 as well as the proposed areas of operation andoperation hours per year.The onsite operation can be described as: Mining 24 hours a day CHPP 24 hours a day Road Transport 24 hours a day Mining Fleet as per Table 2.1 ROM 5.25 Mt per annum Overburden 55,000,000 bcm per annumTable 2.1Equipment Utilisation – Maximum Production YearTypeMobileEquipmentTypeExcavatorExcavatorModel # Location # ofPC8000-6RH340BScheduled to work fromexisting surface to approx60m below surface.Scheduled to extractoverburden until thePC8000's arecommissioned.
