Application Analysis of Hydraulic Fracturing Technology in Coal Seam Fracturing Engineering
There are serious deformations and a large amount of support work in the surrounding rock of the transportation channel and cutting hole of the 3110 excavation face in Yinjiagou Coal Mine.According to the roof conditions and construction conditions of 3110 working face,hydraulic fracturing technology is used for construction,and some plots are selected for industrial test.Through the analysis of monitoring data,it is found that the deformation of the two sides of the roadway and the roof has been reduced to a certain extent,and the reduction of floor heave deformation is the most significant.
