Underground limestone mining is commonly used when a specific rock layer is desired or in areas where there is thick material overlying the desired rock (Mengistu et al 2000) Conversely surface limestone mining involves removal of limestone “rooms” leaving regularly spaced “pillars” in place to support the overlying roof.
The limestone is soft and easily worked when quarried but once the quarried rock dries it becomes case hardened that is its surface becomes harder and resistant to weathering Indiana Limestone is a freestone which means that it has no preferential direction of splitting It can be planed turned on a lathe sawed and hand worked.

In coal mining regions limestone is prevalent and therefore is the least expensive buffer material This led to construction of open limestone channels to pre treat AMD effluent Open limestone channels raise the pH of effluent by the reaction of calcite with carbonic acid CaCO 3 + H 2 CO 3 → Ca 2+ + 2HCO 3 Complications arise when.
