Abstract

In the midst of an energy crisis, coal remains essential to the energy mix of many countries. Over time, coal reserves inevitably deplete, and as a result, coal mining progresses, and mines are closed and abandoned. Abandoned mines continue to emit methane for many years after closure, yet their emissions remain uncontrolled and unmonitored in many coal-producing regions. Closed mines may offer a small but significant opportunity to exploit a clean energy resource, known as Abandoned Mine Methane (AMM), which can be extracted and used. The capture and use of AMM offers many benefits, such as improved safety, air quality, and health, energy supply, and environmental performance. Some technologists can recover methane from abandoned coal mines. Methane gas from abandoned mines (AMM) is extracted through drillings carried out from the surface or through abandoned pipelines in the main opening works, works which, after closure, become methane gas accumulation tanks. In this case, the extraction solution adopted is determined by the closure solution. The paper will present details on the environmental and safety impacts of AMM, as well as techniques for capturing and using methane from abandoned mines (AMM).
