2021.7.15 An alternative to the conventional drill and blast method is the use of rippers. Rippers can be used for limestone mining as limestone is a ‘rippable’ sedimentary rock (refer to Sect. 3.1.1) Using rippers in small mines or for a group consisting of more than one mine is economical and productive.
