Probing into Caving Method of Roadway in Steep Seam |
| |
| Abstract: | The test of caving mining of roadway in steep sesm has got better effect in Jia-he mine.This mining method has the feature of high recovery rate,low la-bor strength low production cost ventilation under full negative pressure and better safety conditions and can be used as a new method for the ex-trac tion of steep medium-thick coal seams.Preventionand Controlof ShockBumpin inflammableExtra-thick Seam(40)—Shock bump is one the major disasters threatening safe pro-duction in coal mines.This paper,based on the analysis of the geological con ditions in Qian qiu Mine,put forward appropriate preven tive and con-trol measures for the shock bump,good engineering re sults and consider-able economic benefits were obtained,which can be useful in the min ing of in flammable extra-thick coal seam with shock bump. |
