    • Environmental Hazards of Limestone Mining Education 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.

    • Ventilating Large Opening Mines mines Since many limestone mines operate at shallow depths, drift portals are common at these operations. Operations at depths up to 61 m (200 ft) are ventilated using airshafts or slopes, the latter also providing access. Still deeper large opening mines such as lead/zinc mines and salt mines use shafts for access and ventilation.
