大采高综采工作面煤壁片帮机理及其控制技术研究

Study on Mechanism and Control Technology of Coal Wall Spalling in Fully Mechanized Coal Mining Face with Large Mining Height

以18104大采高综采工作面为研究对象,从煤壁片帮形式和片帮影响因素等方面分析了大采高工作面煤壁片帮机理。结合该工作面开采实践,给出了工作面煤壁片帮控制措施,通过控制的措施的实施,有效降低了大采高工作面煤壁片帮率和片帮程度。

Taking the 18104 large mining height fully mechanized working face as a example,from the forms and the influence factors of the coal wall spalling to analysis spalling mechanism.Combined with the practice of exploitation of the working face,and gives the working face coal wall tablets help control measures,through the implementation of control measures,effectively reduce the large mining height working face coal wall spalling rate and degree.
