Mine Shaft Project

Millennium just completed a project that was a first for our company, and too interesting not to share.

A development project was set to start on the site of the Old Centennial Mine in Louisville, Colorado.  To make way for the new buildings the old mine shaft had to be cut down so it could be safely capped below grade.  We cut the shaft down 14 feet in two separate phases with a Pentruder wall saw in order to minimize vibration to the hundred plus year old concrete.  As they excavated the shaft down there was a time capsule of old liquor bottles, jars and other strange materials from possibly when the mine was closed.

This was an interesting project and we had fun researching what we could about the old mine. Below is a picture of the shaft before they pulled the last sections down, and the mine cap from the State of Colorado.
