露天掘り鉱山の運搬トラックについて、ディーゼル車とバッテリー電動車を同一生産条件下で環境・経済比較した研究。電動車は初期投資が高いものの、年間CO₂排出を約68〜75%、運営費を約35〜45%削減できる。投資回収期間は電力価格や電池交換費に依存し約5〜7年と試算され、鉱山の脱炭素化と長期コスト削減に有効と結論づける。
English
This study compares diesel and battery-electric haul trucks under similar surface-mine conditions, covering fuel/electricity use, CO2 emissions, OPEX, maintenance, life-cycle costs, NPV and payback. Electric trucks cut annual emissions by ~68-75% and operating costs by ~35-45% despite higher capex, with payback of ~5-7 years depending on electricity and battery-replacement costs. Haulage electrification is an effective route to mine decarbonization and lower long-term costs.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
鉱業は日本の資源調達・Scope 3排出と密接に関わる。電動化の投資回収データは、資源企業の脱炭素投資判断やSSBJ開示における移行計画の根拠として参考になる。
In the global GX context
Mining electrification connects to Scope 3 and transition-planning disclosure under ISSB/TCFD. The quantified payback and emissions-reduction figures offer concrete evidence for transition finance and capital-allocation decisions in hard-to-abate sectors.

📄 Abstract（原文）
Surface mining operations rely heavily on haul trucks for overburden and mineral transportation, making them one of the largest contributors to energy consumption, greenhouse gas (GHG) emissions, and operating costs (International Council on Mining and Metals [ICMM], 2023; International Energy Agency [IEA], 2024) . With increasing emphasis on sustainable mining and carbon neutrality, battery-electric mining trucks have emerged as a promising alternative to conventional diesel-powered haul trucks (McKinsey & Company, 2024; Deloitte, 2024) . This study presents a comparative environmental and economic evaluation of diesel and electric mining trucks operating under similar production conditions in surface mines. The assessment includes diesel fuel consumption, electricity consumption, carbon dioxide (CO₂) emissions, operating expenditure (OPEX), maintenance costs, life-cycle costs, and economic feasibility indicators such as Net Present Value (NPV) and payback period. Results indicate that electric trucks significantly reduce direct greenhouse gas emissions and operating costs despite requiring higher initial capital investment. Based on a representative mine operating 6,000 hours annually , electric trucks reduce annual carbon emissions by approximately 68–75% and operating costs by nearly 35–45% compared to diesel trucks. Economic analysis demonstrates that the higher purchase cost can be recovered within approximately 5–7 years , depending on electricity prices and battery replacement costs. The findings highlight that electrification of haulage systems represents an effective strategy for improving mine (Kumari, V. (2023). sustainability while reducing long-term operating expenses, consistent with recent trends in mining decarbonization and fleet electrification (ICMM, 2023; IEA, 2024; McKinsey & Company, 2024) .
