Abstract In order to analyze the influence of mining thickness of fully mechanized caving face on the peak position of advanced abutment pressure, No. j7401 fully mechanized caving face of Helin Mine was taken as the research object. The relationship between mining thickness of fully mechanized caving face and the peak position of advanced abutment pressure was studied in depth through theoretical analysis. Through theoretical analysis, it was concluded that there was a linear relationship between the mining thickness and the peak position of the advanced abutment pressure, and the distance between the peak position of the advanced abutment pressure and the coal wall of the working face increased with the increase of the mining thickness. The linear relationship between the mining thickness and the peak position of the advanced abutment pressure was established by the least square fitting method, which verified the conclusion of the theoretical analysis. The slope of the linear relationship between the mining thickness and the peak position of the advanced abutment pressure in the j7401 working face was 1.311. The research conclusion can be used to predict the peak position of advance abutment pressure at different mining thicknesses.

Key words： advancing abutment pressure fully-mechanical caving mining mining thickness peak position
