| Abstract: | A Simple Mechanical Impact System (SMIS) was developed recently as a non-explosive seismic source. The SMIS consists of an
impact head, a steel rod with extensions, and an anchoring system. The system is small and simple, and can be conveniently
installed in a shallow borehole oriented in any direction. The SMIS was developed to address two problems commonly associated
with non-explosive seismic sources: insufficient seismic strength and lack of repeatability. Field tests have shown that it
is possible to produce clear and repeatable signals with this system even when the SMIS is installed in a coal seam. |
