Longwall mining is a mining method exceptionally adapted to coal mining.
Although this method is quite efficient for coal mining, it presents certain impacts on the environment.
Let’s explore some of these impacts. They are listed and explained below:
- Land Subsidence
Subsidence occurs as the goaf collapses and the overlying ground sinks. This can cause infrastructure damage, disrupt water flow, and even endanger settlements. Mitigation measures such as leaving coal pillars or injecting grout can reduce subsidence but cannot eliminate it.
- Water Pollution
Contaminants can be released into groundwater and surface water sources because of mining activities. Water quality and aquatic ecosystems are jeopardized by coal dust, acidic drainage from waste rock, and unintentional spills. To mitigate these effects, responsible waste management and treatment are essential.
- Air Pollution
Coal dust from mining and blasting can travel long distances, contributing to air pollution and respiratory problems in nearby communities. Dust control and monitoring are critical for mitigating this impact.
- Greenhouse Gas Emissions
Coal is a fossil fuel, and its extraction and combustion significantly contribute to greenhouse gas emissions, hastening climate change. While longwall operations in Indonesia strive for efficiency, their contribution to overall emissions remains significant. The urgency of transitioning to cleaner energy sources, such as the Indonesian government’s ambitious renewable energy plans, becomes clear.
- Biodiversity Loss
Mining operations have the potential to disrupt ecosystems, fragment habitats, and endanger plant and animal species. Responsible planning and restoration efforts are critical for mitigating biodiversity impacts.
