Hydraulic weakening technology for unsupported top coal at the end of fully mechanized caving face
To address the issue of excessive unsupported top coal length and delayed caving at the end of a fully mechanized caving face, a hydraulic weakening technology for face-end top coal in steeply inclined thick coal seams was proposed based on the coal-breaking and cavity creation method using high-pre...
