Abstract: Taking the history data from 802 unmanned mining workface of Huangling No.1 Coal Mine as the sample, the paper carried out statistical analysis from automation following and manual intervention, focused on production effect of automation following and summarized the main part of the lack of efficiency of coal face automation production and the common operation of manual intervention. According to the special data analysis, the paper proposed reasonable suggestion for unmanned working face production model to achieve the purpose of "reducing people and increasing efficiency" of unmanned technology.
