Show Friday. September IS. 1957 TOE WESTERN MINERAL SURVEY Pace 2 - New Drilling Method Rochet Jet Principle Now Used WESTERN MINERAL SURVEY NXWB 421 Church 1402 Curtla The rocket jet principle used to power our modem jet aircraft and missile weapons is now being put to industrial use. On toe gigantic St. Lawerence Seaway project, blast hiles are being sunk in rock with a flame process known as jet piercing. Developed by Linde Company, Division of Union Carbide Corporation, the new process works on toe rocket principle and makes it possible to pierce rock at speeds up to ten times faster than conventional drilling methods. - CIRCULATION Phone IU Alpine Street St., Denver ADVERTISING EU Sett Leko City.

In addition tor the increased g speeds of penetration, Lindes process makes it possible to chamber blast holes. Chambering consists of enlarging the blast hole at any depth so that extra explosive charges can be placed exactly where they are needed. The operator simply lifts the blow pipe off the bottom of the hole and lets the jet blast away. This induces more spalling at the desired spot and produces a bottle-shape- d cavity, capable of a explosive charge. larger holding Since Jet Piercing harnesses thermal energy instead of mechanical energy, the new process is also eliminating the maintenance problems associated with chum and jackdrills, pneumatic drills, .' hammers.
