The limestone is off-white and has a microcrystalline structure. The limestone layer is nearly horizontal, with a strike of approximately 240°–280° and a dip angle of 15°–25°. The surface coverage is a Quaternary loess layer (Q 2–3) and an artificial soil layer. The loess is sandy brown and contains caliche nodules.
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. The biggest problem in small ...
