冲击地压 岩体突然破坏，瞬时释放大量能量，伴有声响和震动的地压现象。如岩石突然突出或弹射，岩柱崩溃，煤、岩与瓦斯突出等。可一次破坏岩石几吨至上万吨，巷道几米到几十米，还可能波及全矿，造成伤亡，或使部分矿体无法开采。有记载的冲击地压，以英国最早，发生于1738年；1933年发生在抚顺胜利煤矿的冲击地压是中国的最早记载。 冲击地压在煤矿、金属矿、隧道中都可能发生，其命名与分类很不一致。有的将有声响的岩石突然破碎，称为岩爆或煤炮；将引起矿区地震的称矿震；将瓦斯煤矿采掘工作面发生的煤与岩石突然抛出称瓦斯突出。有的将上述现象统称矿山动力现象。 岩体突然破坏的原因，在于破坏的地点贮存能量远大于变形破碎所需要的能量。贮存的能量的大小与其所处地层深度、岩性、地质构造以及采矿方法等密切相关。在岩石的凝固与沉积过程中，各成分收缩不同，有可能形成凝固应力。由于岩体处于三轴压缩状态，这些能量可长期保存。地下工程破坏了岩体的平衡，表面围岩处于双轴应力状态，使变形破碎所需的能量大为减小。在岩体破坏后，过剩的大量能量又将破碎岩石抛出，造成周围岩体震动。脆性岩体的破碎速度很快、很突然。如果岩石中含有高压气体，原来受高应力控制，闭锁在孔隙中，随着应力逐渐减小，将缓慢渗出。一旦岩石突然破碎，应力突然减少，气体来不及渗出,便猛烈膨胀,把岩石"炸"成很细的粉末，形成气石流，一起抛出。这又使应力重新分布，可能再次使围岩破坏、粉碎、搬运。几番交替作用，规模更加扩大。 防止冲击的主要措施有：开采解放层；合理布置巷道位置；合理选择开采顺序和支护方法；消除孤立煤柱，避免应力集中现象；对厚层坚固顶板进行处理，降低煤柱的支承压力；向岩层注水或软化剂;在岩层内钻孔,预先释放一部分能量和气体；用水力冲刷或震动爆破，扩大钻孔破岩效果。其中最有效的区域性措施是开采解放层。 用地质力学及地球物理方法，配合岩体应力和岩体移动测量，利用声发射技术和钻屑等方法，测量岩体内部的破碎情况或岩粉、煤粉的数量，可作冲击危险性预报。岩体破碎前产生微小破裂，并发出声响和微震，故可用微震监测方法，预报冲击地压。
