BLAST HOLE LINER SYSTEM AND METHOD FOR THE SAME

摘要

The present invention relates to a method and apparatus providing a blast hole sealing system (100) configured to substantially seal explosive material in a blast hole (10) from moisture. The blast hole sealing system includes a securing structure (110), a cap member (120), a tubular liner and an air compressor (130). The securing structure is operable to be disposed over an upper portion of the blast hole. The cap member defines a nozzle opening (124) and a liner passage (126) therein and is operable to attach to a top portion of the securing structure. The tubular liner includes an unexpanded configuration (154) having a length with an openable-expandable end (156) and a sealed tail end (158). The openable-expandable end is operable to be disposed through the liner passage in the cap member so that an end portion disposed therethrough is invertedly opened in an expanded configuration and operatively secured to the securing structure
