Analysis of Support Adaptability at Fully Mechanized Mining Face in Weak Surrounding Rock

Based on in-situ pressure monitoring of 1501 fully mechanized mining face in Shuanglong Coal Mine, initial and periodic weighting distance, supporting strength of support were determined, the strata behaviors laws of fully mechanized mining face in medium thick seam of weak surrounding rock are obtained based on the analysis. Support adaptability of working face are analyzed and discussed.
