| Abstract: | Based on the key strata theory in rock's control,the paper presents an analysis of the breakage and movement regularity of the surrounding-rock,the calculation of the filled body's stress with the help of elastic-plastic mechanic theory,and the conclusion of the ration of coal cement water according to experiment.The successful study on the engineering practice not only verifies the feasibility of theory and technique of gob-side entry retaining in FCF,but also shows obvious economic and social benefits. |
