| 摘 要： | 徐州矿区的6对矿井采掘活动达千米,巷道埋深大,矿压显现明显,岩巷施工不久相继出现拱形部分变形,巷道底鼓。在大断面岩巷拱顶采用加密锚杆支护试验,探索了控制深部岩巷变形新方法,并在工程实例中应用,较好地解决了施工巷道及岩巷修护变形的问题。

| Abstract: | Mining and driving activity of 6 couples of mines in Xuzhou Mining Field are being done under ground over 1000 meters and depths of roadways are large. Top arch distortion and floor heave occurred due to distinct underground pressure. Dense bolt supporting test was made at top arch of rock roadway with large section. This is a new method for controlling distortion of deep rock roadway and it preferably settled distortion problem during roadway constructing and repairing. |
