FIELD: oil and gas production.
SUBSTANCE: axial line of driven tunnel is determined with, for example, curve fitting. Data on location of drill platform on axial line of the tunnel are transmitted to the control panel; navigation plane of the blast holes placement layout is arranged on axial line of the tunnel. The initial point of set of the blast holes is positioned on the axial line of the tunnel considering length (L) of the blast holes set. Additionally, the final point of the blast holes set is arranged at distance corresponding to length of blast holes set from the initial point; the coordinate system of blast holes placement layout is directed to facilitate one of its axes running from the initial point to the final point. Finally, various systems of coordinates are utilised.
EFFECT: new and improved procedure for directing layout of blast holes placement in curvilinear tunnel, also development of soft ware for implementation of procedure and drill rig.
