    A foremost element of the mining process is breaking up the rock. This breakup is accomplished by detonating volatiles set in blast holes. The rock face to be gusted is typically 40-feet in width by 20- to 25-feet high. A premeditated pattern of 40 to 50 horizontal holes are drilled for the dimensions of 2 inches wide by 12- to 14-feet deep

    Blasting operations create significant problems to residential and other structures located in the close proximity of the mines. Blast vibration is one of the most crucial nuisances of blasting, which should be accurately estimated to minimize its effect. In this paper, an attempt has been made to apply various models to predict ground vibrations due to mine blasting

    Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust
