The further exploitation of this coal reserve will decrease the<br>costs of preparation of underground mines and granting mining rights and depreciation of infrastructure<br>assets. Moreover, it will help reduce the loss of non-renewable resources and contributing to the<br>sustainable development of Vietnam’s coal industry.</p&gt;}, number={2}, journal={Inżynieria Mineralna}, author={DINH , Van Cuong and NGUYEN , Anh Tuan and TRAN , Van Thanh and NGUYEN , Thi Hoai Nga and DUONG , Duc Hai}, year={2021}, month={grudz.} }
