综采面运输巷机械化原巷充填采煤工艺研究

Research on Coal Mining Technology of Mechanized Original Roadway Packing in Fully Mechanized Mining Face Transportation Roadway

针对永定庄煤矿2104工作面围岩特点,通过分析原巷充填巷道围岩力学特点,采用原巷充填采煤工艺进行巷道围岩稳定性控制,即将充填材料输送到充填模箱内,固化形成的隔离墙配合超前支护液压支架降低巷道围岩移近量,保证工作面快速高效安全回采。

In view of the surrounding rock characteristics of the 2104 working face of Yongdingzhuang Colliery,the mechanical characteristics of the original roadway packing and surrounding rock have been analysed,and the original roadway packing and mining technology has been used to control the stability of the roadway surrounding rock,which ensures fast,efficient and safe mining of working face.
