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 ...

Anthropogenic activities involve extracting the transformation and use of natural resources. During the process of extraction of useful mineral substances on the surface or underground, particles or gases appear in the working environment resulting from the removal or natural release from the rock mass. The process of transformation of useful mineral substances is carried out on the surface in closed enclosures, and involves the use of complex technological processes. During these technological processes, gases, m...
