NOVEMBER Rev May 1, Mine gas, any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, “vapour”). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH 4) and is highly inflammable and explosive when present in the air in a proportion of 5 to 14 damp, or carbon monoxide (CO), is a particularly.

    You can solve drainage problems and create an attractive landscape feature at the same time with a dry creek bed. Build a creek bed to direct water away from a low spot in your yard.
