摘要
Abstract
Through carrying on the field strata control observation of 1301 fully mechanized caving face in Guojiahe coal mine,the movement characteristics of roof rock is analyzed,and the strata-pressure behavior is mastered too.There is certain reference in studying strata-pressure behavior and determining reasonable working resistance of support on fully mechanized caving face of Linbei coal field.关键词
