崔庄煤矿综放动压相向掘进沿空巷道非对称支护研究
Research on Asymmetric Support of Roadway Along Goaf During Fully Mechanized Caving Dynamic Pressure Opposite Direction Excavation in Cuizhuang Coal Mine
摘要
Abstract
The 33upper08 working face transportation roadway of Cuizhuang Coal Mine is being excavated towards the direction of the 33upper07 coal mining working face,which is affected by the mining advanced support pressure and lateral support pressure of the 33upper07 working face.The stress environment of the roadway is complex,and the support difficulty is large.A method combining on-site investigation,numerical simulation,and industrial testing is adopted to analyze the surrounding rock deformation amount at each stage of the roadway and the stress change laws of the roof and side walls.It is found that the roof and side walls along goaf have severely deformation under the influence of mining dynamic pressure in the 33upper07 working face,design and optimization of the roadway are conducted.The industrial testing research shows that the optimized asymmetric support scheme can effectively control the deformation of the roadway surrounding rock,and basically guarantee the normal use of the roadway within its service life.关键词
