Feb 18, 2021· The chipping and grinding processes are the basis for understanding rock cutting during TBM excavation in hard rock conditions. The chips are produced when tensile fractures created by adjacent cutters propagate parallel to the tunnel face and coalesce whereas grinding occurs when fractures do not fully propagate through the rock and only fines are generated.

What is the limestone's mining process? Quora

Limestone deposits are found throughout the world. They are “mined” in a process known as “quarrying.”. This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined. In this case, the rock has holes drilled in it which are filled with explosive and they
