矿井深部采区顺槽的围岩承受地压大、变形严重,以前的支护形式不能有效地控制围岩的变形和破坏,而“锚背”支护、框式可缩性支架及其联合支护,不但支护强度高,而且性能好,支护效果好,在生产现场可根据具体的地质条件选用。
Surrounding rock along the trough in the deep mining area of the mine is under large pressure and serious deformation, and the former support forms can not effectively control the deformation and failure of the surrounding rock. However, the “anchor back” support, frame collapsible support and Its joint support, not only high support strength, and good performance, good support effect, in the production site can be selected according to the specific geological conditions.
