Abstract In view of the problem of large area roof leakage accident in shallow buried deep fully mechanized working face when passing through the structural belt, according to the actual situation of 1805 working face in Shaping Coal Mine, the causes of roof leakage are analyzed, and the treatment scheme after roof leakage is summarized, and the technical measures for advanced prevention of roof leakage are put forward. The field application effect is good, which has certain reference significance for the rapid passage of shallow buried deep fully mechanized working face through the structural belt.
