| Abstract_FL | In the process of coal mining,along with the improvement of mining equipment level,in order to improve the coal resource recovery rate,the proportion of super-high fully mechanized face at one time has been increasing year by year,and the chance of topping and sheeting has also increased.This paper introduces the prevention and control technology of fully mechanized face from three aspects:injection of polymer material,laying false roof and dealing with large gangue,which provides a clear and effective solution to the problem of super-high fully mechanized face. |
