Abstract
In order to drill "dry" wells in snow-firn and ice strata, the SPbSMI (TU) Department of Drilling Technology and Technology is developing a technology of mechanical drilling with bottom-hole air circulation to remove cuttings. The electromechanical drilling tool for drilling with bottom-hole air blowout is similar to the previously developed KEMS-112* drilling tool for drilling deep wells filled with filling fluid.
