Abstract
This report documents the process of site selection, instrument installation, data acquisition, and preliminary data analysis followed to characterize the physical response of overlying strata to longwall mining. A system of surface, subsurface, and mine level instrumentation was installed at the Allen Mine in Weston, Colorado, where the overburden ranged from 600 to 900 ft thick. A preliminary analysis of the data showed the system to be operative and strata response to be similar to that reported for other subsidence monitoring case histories. Recommendations for continued monitoring of the instrumentation systems are presented.
