This study proposes the <em>Timber-</em>Support <em>Risk Mitigation Framework</em> (<em>TRF</em>), a cost–benefit and risk assessment approach integrating rock mechanistic principles and eco-friendly materials to enhance excavation stability under resource constraints in ASM. Using compression tests and probabilistic analysis, eight timber-based support configurations were evaluated for rock strength improvement, probability of failure (<em>P</em>_{<em>failure</em>}), and installation costs. Additionally, the standard deviation (<em>SD</em>) and variance (<span><math><mrow><msup><mi>σ</mi><mn>2</mn></msup></mrow></math></span>) were incorporated to quantify the uncertainty of rock strength improvement and utilized to calculate the probability of failure. Results show that a staggered support pattern (SSP) with small-sized soft timber delivers the highest rock mass stability, improving rock strength (<em>UCS</em>) by +82 % and reducing <em>P</em>_{<em>failure</em>} to 0.2, at the lowest cost range of $100–$150 per 1.2 m advance. Conversely, large-sized soft timber in SSP yields minimal strength enhancement (+34 %) and incurs the highest costs ($700–$750) with the highest <em>P</em>_{<em>failure</em>} of 0.7. Uncertainty analysis also highlights the importance of consistent <em>UCS</em> performance by prioritizing ground support systems for reliable tunnel stability predictions. Practical implementation pathways were also provided, which include local cooperative-led training, micro-grants, standardized permits and timber specifications, and policy integration to institutionalize ground-control practices in ASM. The proposed innovative rock mechanics-based cost-benefit framework, TRF, offers a simple, low-cost decision-making tool for ASM operators, enabling safer, more sustainable extraction of critical minerals.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"113 ","pages":"Article 105853"},"PeriodicalIF":10.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on 16 months of ethnographic fieldwork, this study examines how nostalgia and emotional attachment foster both continuity and resistance in post-mining contexts. Rather than focusing on the victimization of mining communities, this study emphasizes their agency and emotional ties that drive sustainability strategies.

In Australia, mining represents a crucial sector and plays a central role in the global decarbonisation movement. However, material haulage operations are the primary source of emissions within mining activities. This paper explores the current alternatives to traditional diesel-powered haul trucks, focusing on trolley and battery-electric powertrains as potential solutions for decarbonising mining haulage systems. A case study in mining was developed to compare these applications using the Well-to-Wheel (WTW) analysis method. This approach evaluates their environmental benefits and assesses whether they can help mining companies meet their emission reduction targets in the short-medium term. A new term, Equivalent Emission Factor (EEF), is introduced as a comparative standard for evaluating the emission reduction effectiveness of these alternatives. The results of the mining case study simulation indicate that Hybrid Diesel Trucks (HDT) perform exceptionally well in reducing emissions under the 2023 emission factor conditions, particularly in regions with a higher concentration of coal-fired power plants. In contrast, battery-electric alternatives are expected to outperform HDT as the share of renewable energy increases in these regions. Ultimately, battery-electric alternatives emerge as the most promising option among all alternatives, due to their high energy efficiency and reliance on fully electric power in the 2030 scenarios. The research findings will assist mining decision-makers in formulating effective strategies for the adoption of various mining truck alternatives, thereby maximising environmental benefits in their decarbonisation journey.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"113 ","pages":"Article 105826"},"PeriodicalIF":10.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coal rents show no significant impact, and forest rents demonstrate a sharp increase in EF with positive shocks and a reduction with negative shocks.

The findings show that OPU has a unidirectional, significant causal effect on coal production, total fossil fuel production, and total primary energy production. For renewable energy, both positive and negative time-dependent relationships are identified. Wavelet analysis reveals that the link between OPU and energy production varies periodically: price uncertainty encouraging renewable energy investment in some periods but creating volatility in conventional energy output in other periods. These results confirm the role of price uncertainty as a key determinant of energy market dynamics, consistent with the international literature. The study highlights that increasing the diversity of the energy portfolio, supporting investment in renewables, and developing flexible policy instruments are critical to the security and sustainability of the energy supply.

In addition to the traditional sources of external shocks, such as commodity and financial fluctuations, this study examines the impact of productivity shocks from key trade partners within the SSA region. The findings stem from a Global Vector Autoregressive (GVAR) model encompassing 21 SSA nations, categorised based on oil-rich, other resource, and non-resource characteristics using a quarterly data series from 1990 to 2022. The research controls for shocks originating from commodities, foreign direct investment (FDI), and productivity shocks from major trading partners, including the United States (U.S.), the United Kingdom (U.K.), China, and Europe. The results show that trade integration is a significant conduit for transmitting external shocks, affecting GDP performance across the SSA region and within distinct resource-endowment groups. Empirical results highlight diverse contributions and varying impacts from the examined external shock sources, with productivity and financial shocks emerging as the most influential factors. Notably, the study identifies productivity and financial shocks from China, the U.S., and the Eurozone as the most influential factors and primary drivers of growth performance in the region.

In these contexts, collective memory and identity may play a crucial role in shaping local perceptions and community support. This study investigates how collective memory and identity influence community perceptions of mining impacts and support for mine reactivation. We focused on Borralha, a village in northern Portugal founded in the early twentieth century around tungsten mining, whose economy, social fabric, and identity have been deeply shaped by decades of extractive activity. Using a mixed-methods design, quantitative data from a resident survey were used to develop a PLS-SEM model to test hypothesized relationships. Qualitative data from focus groups were analysed through content analysis to contextualise and deepen the quantitative findings. Results show that collective memory and identity have a direct positive effect on perceptions of mining impacts, which significantly influence their support for mine reactivation. The findings indicate a significant indirect effect of memory and identity on support, mediated by impact perceptions. Qualitative findings further substantiate the quantitative findings.
