| Abstract: | In view of the geological conditions of No.15 coal seam in Shennong Coal Industry,combined with the coal mining method of mine design,according to the theory of"transfer rock beam",the support strength,working resistance and support height of hydraulic support in the working face are analyzed,and it is determined that the ZZ8000/23/47 type four column support cover type hydraulic support can meet the safety production.Mine pressure observation shows that the hydraulic support of the working face has a certain amount of surplus resistance and has achieved good support effect. |
