摘要
端尾区是巷道和综采工作面的交汇处,超高巷道机尾支护系统在端尾区替代了矿用单体液压支柱和金属顶梁配合使用的支护系统,解决了端尾区的空间、矿压、强度等支护技术难题。
The end tail region is the intersection of the mining tunnel and the comprehensive mining face. The ultra-high roadway tail support system replaces the supporting system of the mining single hydraulic prop and the metal top beam in the end-end area, which solves the technical problems of space, mine pressure and strength in the end-end area.
