Determining the working status of the production organization structure in the mechanized longwall when the negative impact factor has appeared

Tóm tắt

For the purpose of ensuring sustainable development, one of the important factors is to increase labor productivity and minimize the number of workers directly working in the mine. In the context of increasing requirements for underground coal mining, the number of workers tends to decline due to shifting to other types of economy. Therefore, the mechanization investment in coal mining is the inevitable destination, which guarantees the long - term strategic development of the coal mining industry. Although the mechanized mining has obtained several achievements, the annual coal mining output is still not high, specifically reaching 73.8%; 51.3%; 61.4% according to the plan respectively for the years of 2013, 2014 and 2015. A total of mechanized lines has been invested and applied in Vietnam National Coal - Mineral Industries Holding Corporation Limited, but there are only six lines in operation until at this time. For five recent years, when the mining industry has accumulated a lot of experience in using mechanization technology, it is found that the potential factors causing production interruption have resulted in the effectiveness of these longwalls not achieved as expected. Summary of advantages, difficulties, and unsuccessful implementation of mechanization technology in the condition of Quang Ninh mine area has shown a big gap in production organization that should be specifically studying. In this study, the author wants to build a basic background in determining the impact of potential factors conscious of the longwall mechanized.
