Freeze-hole construction technology applied to in-situ mining for oil shale

摘要

This paper briefly introduces the application of the freezing technology in the field of oil shale mining and the principle of the freezing technology. It also describes different characteristics of application for in situ mining for oil shale from other of underground works for the freeze-hole technology as well as the risks inherent in this technology. The operational parameters for the freezing technology also need to be studied in depth. As for the broad applicability of the freeze-hole technology, the freezing technology would be applied to the exploitation in other fields of new energy.
