摘要
针对端头支护中存在的问题,为适应工作面快速推进的要求,对传统的采用"一主两副"端头支架支护方式进行改革,在王庄煤矿5208综放面试验,成功采用单体液压支柱加金属π型顶梁的联合支护方式管理端头顶板。现场实践表明,新的端头支护方式可满足端头顶板下沉和支护强度的要求。
Based on existed problems of face-end support and adapt to the requirement of quick thrust on working face, the traditional face-end support patterns have been reformed, and the new manages face-end roof in united method of combining single hydraulic prop and type - π metal cap have been successfully applied in 5208 fully- mechanized mining face. The practical engineering shows that the new face-end support pattern can meet the requirement of face-end roof covergence and support strength.
