Vietnam's domestic coal production is growing fast and is expected to reach 68.9 million tonsin 2030, nearly 1.5 times higher than today. Open-pit mines will gradually reduce production and close,and underground mining coal output will increase progressively year by year and take a leading role.Besides the investment in new mines to achieve these goals, it is necessary to maximize the coal reserveexploited annually of existing underground mine projects, which its coal reserve in pillars protectingroadways currently accounts for 12−15%. The further exploitation of this coal reserve will decrease thecosts of preparation of underground mines and granting mining rights and depreciation of infrastructureassets. Moreover, it will help reduce the loss of non-renewable resources and contributing to thesustainable development of Vietnam’s coal industry.
