System for rapidly boring through materials
The present invention is a self-contained, high-energy liquid rock-boring system that will bore a small-diameter access hole [ 5 ] several hundred meters through hard granite and other obstacles within minutes of deployment. It employs a land unit [ 100 ] platform subsystem [ 1000 ] with an energetic fluid fuel reservoir [ 1300 ] and a boring subsystem [ 3000 ] having a plurality of pulsejets [ 3100 ]. Each pulsejet [ 3100 ] repeatedly ignites the energetic fluid [ 7 ] causing a plurality of rapidly-expanding gas bubbles [ 3250 ] which create and force a plurality liquid slugs [ 10 ] ahead of them rapidly out through a nozzle [ 3260 ] causing the slugs [ 10 ] to impact against materials ahead of the nozzles [ 3260 ], boring an access hole [ 5 ]. The system also employs an umbilical subsystem [ 2000 ] connecting the boring [ 3000 ] and the platform subsystems [ 1000 ]. The system can be used to rapidly bore an access hole [ 5 ] to provide air and resources to trapped miners. Alternatively, the system may also be used to bore an access hole [ 5 ] to underground threatening targets to neutralize them.
