Mine caps

Mine Caps are typically used to prevent access to old, abandoned mines. People, especially the young, like to explore their surroundings but may not fully understand the dangers inherent within, and surrounding, a mine.
== Why Do Mines Need To Be Capped? ==
Cave-ins, poor air quality, wet slippery surfaces, etc. are real dangers when entering a mine, but even the surrounding area can be dangerous. Older mines may have been covered with logs or wooden beams with loose rock and soil over the top. These fail over time, creating sinkholes, that may not be visible on the surface, until enough weight collapses it.
