Abstract: This paper described working surface profile parameters and belt roadway tunneling of 18303 and mining situation of
18305 in Malan Coal Mine, analyzed two supporting forms before and after roadways of 18303 belt roadway, as well as the effect
of different supporting and the cause analysis, and pointed out its economic benefits with the aims to analyze roadway bolting
parameters within the scope of mining dynamic pressure. Key words: mining dynamic pressure; two displacement; heaving floor; yield tray; send roadway; supporting parameters
