Roof to Floor Closure Rate Instrument for Underground Mines
This citation summarizes a one-page announcement of technology available for utilization. Objective: Provide roof to floor closure rate measurements during underground mining. Approach: An electronic device and rugged potentiometric extensometer were developed to provide a means for measuring total closure and the rate of closure. How It Works: Two potentiometric extensometers are attached to the readout unit. As the roof to floor closure changes, the potentiometric resistance change is measured and displayed. ...FOR ADDITIONAL INFORMATION: Contact: Technology Transfer Officer, Bureau of Mines, Spokane Research Center, E. 315 Montogomery Ave., Spokane, WA 99207.
