Development of structures hole charges based on the criterion of energy intensity drilling massif mountain breeds with hollow

N.I. Zhukova

Abstract


The analytical and experimental studies of physical processes in the interaction of the drilling tool with layers of rocks throughout the depth of the well. It is proved that the efficiency and hole charges seismic safety designs reduces emissions of oversized pieces. In boreholes with cavities from 10 to 40% and allows to decrease seismic effects to 30%

Keywords
