摘要
太平煤矿九采区泵房、变电所由于围岩松软,出现了较为严重的变形显现,虽经翻修,仍未有效控制巷道围岩变形。经采用高强高预应力锚网索支护系统配合注浆加固,使硐室围岩形成高预应力混凝土加固拱,维护了硐室的稳定。
Because of soft surrounding rock, the the chamber of the pumping station and substation of the ninth mining area had appeared seriously deformation in. It eouldnt control the deformation effectively, after repaired several times. High-strength and high pre - stress boh-mesh-anchor support system cooperates with grouting can form reinforcing arch of high pre-stress concrete in chamber sur- rounding rock, and carry out the ehamber＇s stability of chambers.
