A Study and Trial of Using High Water Content Filling Material as Rib Support in No.9 thin Coal Seam in Jincheng Coal Mining Bureau

This paper disscusses the basic characteristics of strata behavior ,the technology of rib support,popularization and application of main types of rib support of roadways retained along previous gob.And analyses the problems and adaptability of this technology in popularization and application.In order to release the tension of coal winning and roadway drivage in No.9 thin coal seam,Jincheng coal mining bureau conducts a study and trial of using high water content filling material as rib support along roadsides.The results indicate that the trial is a success and has the values of popularization,and then set forth some new views on further field tests and popularization.
