摘　　要：通过对“Ｕ”型钢可缩性支架壁后充填矿压观测研究表明：壁后充填使巷道围岩与支架紧密接触，改善了支架受力状况，提高了支架承载能力，巷道维护效果得到改善，巷道断面收缩率仅为２．０５％，是一种比较理想的支护形式，能适应频繁受采动影响的巷道支护。Abstract It was shown through observation and research on ground pressure of Ushape steel yielding supports with filling wall back that wall back filling can made the contact between surrounding rock of roadway and supports more closely, thus improving the force loading condition and raising the bearing capacity of the supports with better support result of the roadway with only 2.05% convergence rate of roadway section. So it was a relatively ideal supporting mode in roadway roadway frequently affected by mining activities.
