摘要
针对煤层倾角变化大、埋藏深导致工作面的支护效果不佳的问题,在分析某矿11853工作面地质、水文等条件的基础上,对不同煤层倾角下巷道的变形及破坏规律进行研究,并以此为基础完成了对某矿11853工作面的支护参数的设计和支护效果的观测,为今后复杂工作面的支护奠定基础。
In view of the problem that the coal seam inclination angle changes greatly and the buried depth causes the support effect of the working face to be poor,on the basis of analyzing the geological and hydrological conditions of a mine 11853 working face,the deformation and failure law of roadway under different coal seam inclination angle is studied,and on this basis,the design of supporting parameters and observation of supporting effect of a mine 11853 working face are completed,which lays the foundation for the support of complex working face in the future.
