The Vietnam Coal and Minerals industrial group has currently invested in the development excavation of coal mine underground construction. Many modern equipment of world famous brands such as: Sandvik, Atlas Copco, Bolt tech... was put into execution. Manual labor of the workers have been replaced significantly. The advanced of construction and labor productivity has already improved. However, so far the performance of the new equipment actually has not been promoted. The reasons can be seen as: Using the device is not suitable for complex construction conditions in Vietnam; the investment is only a model, not focused; of the line equipment, only a modernized equipment (drill rig, excavator), the equipment remains the most backward; drainage maintenance, spare parts not meet the requirements. Even in many fields, the modern equipment no longer used and has been replaced by the more out of dated equipment. The fact is, if no solutions will increasingly hold back the development of the coal mining industry in Vietnam.
According to the coal industry development plan in 2014–2020 period, coal production continued growth and expected 58 million tons by 2020. To achieve this task, there are a great of development have being constructed. According to the annual statistics, in order to exploit 20 to 30 million tons of coal by underground mining method in Vietnam today, Vietnam coal industry has to implement an average of 400,000 m the development. Through the initial survey, the general assessment above the construction in the Vietnam underground coal mines that the research on this problem, the solution at synchronization of the construction, improvement of technological scheme and labor organizations, to improve productivity, increasing of excavation advance should be necessary.
Coal Industry Group - Minerals of Vietnam (Vinacomin) currently has certain investments in the excavation equipment. Many modern equipment of famous world of brands such as Sandvik, Atlas Copco, Bolttech... was put into excavation implementation. Manual labor of the workers have been replaced significantly by mechanization. The advance of excavation and productivity have improved.
