地压现象是（）产生的。
A.
没有掘进巷道以前，上部岩石用本身的重量压着下部岩石，下部岩石对上部岩石的压力产生反作用力，这种压力与反作用力处于一种平衡状态，故岩体内任意一点上的应力都是平衡的
B.
巷道开挖以后，破坏了原岩应力的平衡状态，巷道周围的岩石受力情况发生了变化，围岩应力重新分布，所有的地区都会升高
C.
一般说来，由于力的不平衡，会使巷道周围岩石发生变形、破坏甚至
D.
试验和实践证明，在岩体中掘进巷道后，巷道周边围岩会产生明显的应力集中现象，即巷道周边围岩承受的应力是原岩应力的数倍。如果巷道围岩重新分配的应力没有超过岩体的强度，则围岩只产生轻微的变形及位移；如果超过岩体强度，则该处的围岩就会破坏
