According to the distribution law of three zones in uncovering coal and the relation between the distribution law and delay outburst, the prevention and control technology is brought up, which firstly adopts gas drainage in the coal through drainage hole to release the outburst power by stages, and then intensifies the intensity of uncovering coal and increases the length of stress relaxation zone and stress concentration zone by using the liquid injecting and freezing to prevent the coal rheology. At last, the shoring measures to prevent roof falling is tabled.

根据掘进工作面附近暴露煤体的&三区&分布规律及其与延时突出的关系；提出先采用钻孔抽放石门突出煤层瓦斯等措施分阶段释放煤与瓦斯突出动力源；再用注液冻结技术增强揭开煤体的强度、增加集中应力区和卸压区的长度来防止被揭开煤体发生流变而导致延时突出的防突技术；以及在揭煤后采取迅速支护防止空顶和冒落等防治措施。

On the basis of designing and constructing the anchor man pole- anchor man unites supporting, observing the transmutation of tunnel via installing the monitor and analyzing the dates, educe the conclusion that bolting support in depth high stress is a valid method, give the accordingly economic and reasonable support parameter and put forward the support countermeasure for mining tunnel with high stress at depth.

本文通过对1091-2工作面风运道采用锚杆-锚索联合支护的形式的设计、施工并通过安设监测仪器进行顶底板变形、两帮变形及锚杆受力等数据观测和分析，得出在林西矿业公司深部高应区回采巷道采用锚杆支护是行之有效的支护方式，给出了林西矿业公司锚杆支护安全经济合理的支护参数，并提出深部高应力回采巷道的支护对策。
