Case Studies

The following case studies provide some examples where the best practices discussed in the Best Practice Guidance for Effective Methane Drainage and Use in Coal Mines (BPG) have been implemented at operating mines around the world. The serious consequences of failing to adopt these best practices are also highlighted.
