Environmental Hazards of Limestone Mining and Adaptive

Excavators are used to remove the topsoil and surface miners were used to mine limestone. As no drilling and blasting are involved, there is a reduction in air pollution and high noise generation. The surface miners also have an inbuilt dust suppression system (Indian Bureau of Mines 2014). 4.2.3 Dump Stabilization at Halki Limestone Mine, …

Drilling Cost

One development well will cost 55–88 MM$ plus completion costs (+80%) totaling 99–158.4 MM$. Remember that we will need 13 wells. We may assume that we learn costs while we drill more wells, so let's assume the first 2 wells will cost the 99–158.4 MM$ and the remaining 11 wells will be slightly cheaper.
