Research on Hydraulic Fracturing and Roof Cutting Pressure Relief Technology for Coal Mining Face Roadway
The suspended roof collapse of the 2304 working face in a certain coal mine causes severe deformation of the roadway.The hydraulic fracturing and roof cutting pressure relief technology is adopted to damage the integrity of the roof rock layer and reduce the damage of the roof collapse to the working face.On site engineering practice has shown that the maximum deformation of the roof and floor of the roadway after pressure relief is within the safe range,the hydraulic fracturing and roof cutting pressure relief have achieved good construction results.
