Abstract:The control of hard roof weighting is one of the difficult problems of coal mining. It is an important subiect of strata control theory to find out its rules and provide reasonable controlling methods. The subject is approached in this paper through the site research of two tested coal faces in Mentougou mine. The rules of the movement of roof strata and the manifestation of strata pressure were roughly found out. The results of practical control show that the obtained conclusions tally with the actual situation quite well
Keywords:hard roof  prediction of weighting  roof control  rock beam  Mentougou mine
