Abstract:

In recent years, underground coal companies and mining construction companies of Vietnam National Coal and Mineral Industries Group (VINACOMIN) have invested and applied many new technological solutions as well as modern equipments and materials in the roadway driving, then it has achieved its object. However, the driving work of VINACOMIN still has many shortcoming. For example, the level of mechanization is not high, the speed of roadway driving and the labor productivity is low. In the coming time, the underground coal mines will be more and more exploited deeper, which will be leading to a series of detrimental problems for excavation work that need to be solved. The paper evaluates and analyze achievements and challenges, as well as propose the development orientations of mechanized excavation technology for underground coal mines of VINACOMIN.
