ENGINEERING CONTRIBUTION TO TECHNOLOGY OF BORING DRILLING OF MINING HOLES ON PRICARPATTI AFTER 1939
Keywords:
boring drilling of trunks of mining holes of large diameter, boring drilling of ramified-horizontal mining holes, boring drilling by the reactive-turbine boring, washing liquids, tamponouvannya of mining holes, mastering of mining holes.Abstract
We describe the development of well drilling techno-logies at Precarpathia in 1945-2000. We consider the drilling technologies, where the gas stream is given under pressure, the drilling of large diameter wells, the drilling of superdeep wells and drilling of complex profile wells.
