摘要
本文介绍了四柱支撑掩护式低位放顶煤支架在登封煤田"三软"不稳定煤层的应用;并对比中位放顶煤支架,分析了低位支架在"三软"不稳定煤层的适用情况,在支架稳定性、围岩控制、安全性、生产效率等方面有明显的优势;最后总结了白坪矿使用低位放顶煤支架回采工艺所取得的效益。
This paper introduces Low Caving Mechanized Mining Bracket Support Shield in Dengfeng coal "Three Soft" Unstable Coal Seam applications; And compared with a median caving'support, Analysis of the low bracket in the "three soft" seam unstable applicable, In support stability, rock control, safety, production efficiency has obvious advantages; Concludes with white floor using low mineral recovery processes caving support the benefits achieved.
