Abstract: The present invention relates to an apparatus and in-situ method for immobilizing mine drainage from spent mine works. This apparatus and preferred method are readily adapted for use in any mine, but particularly well-suited for mines which are located on steep hills or mountain sides having limited infrastructure to permit access for utilities and construction equipment. The present invention utilizes known technology for erecting a bulkhead in the portal of a mine drift, providing a distribution system for controlling drainage of mine water collected behind the bulkhead, mixing the mine water with a constituent to form a slurry, and introducing the slurry into the sealed mine. The present invention has the advantage of neutralizing the mine water to make discharges, if any, acceptable; precipitating dissolved metal out of the mine water within the sealed mine; and further sealing fissures that create seepage from the sealed mine.

Abstract: An adjustable template for locating drill hole positions primarily for cabinet doors and drawers. The template consists of a flat rectangular plate having spaced drill guide holes therethrough. The position of the plate with respect to the item to be drilled is established by way of a first elongated rod extending outwardly from one edge of the plate and a pair of spaced parallel rods extending outwardly from an adjacent edge of the plate, each rod having an adjustable edge guide movably mounted thereon.
