This report describes the technical progress on a project to design and construct a multi-
channel geophone array that improves tomographic imaging capabilities in both surface
and underground mines. Especially important in the design of the array is sensor
placement. One issue related to sensor placement is addressed in this report: the method
for clamping the sensor once it is emplaced in the borehole. If the sensors (geophones)
are not adequately coupled to the surrounding rock mass, the resulting data will be of
very poor quality. Improved imaging capabilities will produce energy, environmental,
and economic benefits by increasing exploration accuracy and reducing operating costs.
Here’s what’s next.
