Engineering geology of Kansas city underground spaces

The Bethany Falls and Argentine limestone members provide a high grade limestone aggregates for construction but also excellent areas for underground manufacturing and storage space. Under proper mining this formation will yield large areas that will constant air temperature of 52 degrees F (18 o C) and low humidity levels. Overlying shale or claystone beds provides a nearly impermeable groundwater barrier to mined out areas below. Roof support via rock bolting is almost never needed if sufficient support pillars are created during the mining operation. With minimal finishing of the mine such as a concrete floor and painting the mine space can then be rented with rental receipts soon exceeding the cost of excavation and sale of the rock.
