the limestone formations of the Eastern and Midwestern U.S. can be much higher than the overburden stress. Horizontal stresses in limestone formations have been measured in limestone mines 7 and in many of the areas coal mines 12. Research has shown that the horizontal stress may be explained by the effect of plate tectonics 7, 13. Effect of limestone mining on tree density is demonstrated by the absence of any tree stem in the mined site (Table 2).

Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods. Mining has altered ground-water flow paths affecting the water supply to a calcareous fen. Table 1. Summary table of sites and impacts studied.

Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO 3. The calcium carbonate is originally produced by living animals (such as shellfish). Later, much of it goes into solution in sea water, and then is deposited as limestone. Calcium carbonate gets precipitated when the ...

What effect does the limestone Limestone formations in the United States can be subject to relatively high horizontal stresses owing to the existence of tectonic loading of the limestone strata. Underground limestone mines use the room-and-pillar method, in which 12- to 18-m-wide rooms are typically excavated. The stability of these excavations can be compromised by the horizontal stress, resulting in a rock fall hazard.
