A comprehensive method of field observation, experiment, and theoretical analysis was used to study the strata behavior of thin-coal areas and upward mining sections of No.5310 large-mining-height working face in Chengzhuang Mine. Meanwhile, interval and strength of periodic weighting, rib spalling, roof falling, and their influential factors were studied for roof management. Besides, distribution, range, peak position, and strength of the abutment pressure were studied. The paper proposes caving techniques and roof control measures when the large-mining-height working face passing the thin-coal areas and upward mining sections. In addition, it discusses the relationship between basic parameters and the strata behavior, support stability, support stress, rib spalling and roof stability by quantitative and qualitative research.
