The underground mining is done when the ore is present in more than 100m depth or when the availability of limestone is abundant. Other factors that determine underground mining is that topsoil covering the mineral is hard like rocks. The first process to start underground mining is considering the economical factors.

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. Instantaneous blasting or blasting with delay detonators in mines are executed in circuits.

Mining granite is a very large industrial process. The first step of making a granite slab is to mine the raw granite materials out of the crust of the earth in large, heavy blocks. Granite slabs are attained from specific sites that are known as quarries. Normally, miners choose quarries that are as close to the surface of the earth as possible.
