· Mining Plan For Open Cast Limestone Mining. Mining Plan For Open Cast Limestone Mining cryogenic milling. in principle, size reduction begins when the externallyapplied stress induces sufficient strain within the particles and causes the formation of cracks. the cracks are then propagated through lines of weaknesses in the material, with new cracks being initiated and perpetuated
