Roof cutting mechanism of dense drilling in gob-side entry retaining and determination method of key parameters
To achieve the safe and stable structural condition of the roof along the goaf under the roof cutting by dense drilling method, the stress distribution and fracture process of the roof strata between normal and dense drilling conditions were studied. Based on rock fracture theory and elastic theory,...
