These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.

A small yet very thoughtful devotional book. A beautiful way to promote seeing God everyday in everything.
