What is the caving mining method? The caving mining method is a mining method that achieves ground pressure management by caving surrounding rock. That is, while the ore is falling, the surrounding rock is forced or naturally collapsed, and the empty area is filled to control and manage the ground pressure.
Second, the characteristics of the caving mining method
(1) The caving method no longer divides the nuggets into mines and pillars, but uses the entire nugget as an extraction unit to continuously carry out single-step recovery in a certain order of recovery.
(2) During the mining process, the surrounding rock shall be naturally or forcedly collapsed, and the ore shall be discharged under direct contact with the covered rock. Therefore, this mining method is necessary for the scientific management of the ore discharge.
(3) The mining of the caving method is carried out from top to bottom in one stage. Different from the empty field mining method.
