Abstract Combining with the actual situation of the high caving area at 90110 working face of Shanxi Majunyu Mine, a comprehensive management measure of filling management of the the roof + coal waster slurry reinforcement management was proposed. The results showed that the technology improved the support of false roof and relieved the gas accumulation in the nest wind area; it improved the cementing ability of broken coal rock body and prevented the continued deformation of the working face roof caving, which effectively controlled the expanding range of high caving area and ensured the safe mining of the working face.
