Create concrete slabs for the floor

Aesthetically more attractive, but also possible to add a loss of material if the materials are not deposited on the concrete slabs.
For example, coal is deposited at a place... a mining reserve. Underneath it would form a mixture with the earth and the stone and therefore a possible loss of coal if we don't dig entirely. This principle could be avoided by creating a concrete slab underneath the raw material deposit.

I think something like this is on the Roadmap.
