Dongpang Mine adopted hydraulic fracturing technology to fracture and decompressed the high stresses in the overlying rock layer of No.2 Mine 21113 belt roadway, weakened the influence of the high stresses formed in the mining field on the deep horizontal track roadway. The results showed that after fracturing, the overhanging top area of the working face void area was greatly reduced, which alleviated the influence of the advanced bearing pressure and lateral bearing pressure to the stability of the 21113 roadway and the deep horizontal transport roadway, and solved the problem of maintaining the stability of the roadway.
