Study On Surrounding Rock Control Techniques Of Mining Roadways Of Fully Mechanized Top-coal Caving Face In Thick Coal Seam With Large Mining Height

Strata pressure behavior are more strongly in the practical application and theaccident of working face and roadway strata pressure became more serious In themine production process with fully-mechanized top coal caving mining technologywith great mining height in thick seams. With blot support being a kind ofimportant support form in the world,whether the supporting parameter setting isreasonable or not has an important part in cutting down the support costs andguaranteeing safe. The characteristics of coal petrological physics are thefoundation of coal roadway support study and with the experimental study onuniaxial and triaxial compression and deformation properties, this article appliesthe soft of FLAC3Dfinite difference numerical simulation to do numericalsimulative study for the supporting scheme of2101belt way in Tongxin mine andinspect and inspect and verify the effect. Analysis of the results of surroundingrock ground pressure monitoring show the effect of the scheme is good.
