Cave mining techniques are becoming increasingly popular because they yield high production rates at lower costs.Block caving is a mining method in which blocks of ore are undercut to induce caving,allowing it to break up and be drawn off,pulled by gravity.
崩落开采法能够以更低的成本实现较高的生产率，因此得到了愈加普遍的应用。矿块崩落开采法的原理是对矿块进行拉底，诱发矿体在重力的作用下崩落，从而逐渐分解出矿。
