Abstract

A device and a method for providing a converted blasting pattern coordinate are proposed. The device for providing a converted blasting pattern coordinate includes: a distance difference calculation part configured to preset any one of detonator holes as a reference point, and to calculate each distance difference between X-coordinates and Y-coordinates of the reference detonator hole and the remaining detonator holes; a polar coordinate value derivation part configured to derive polar coordinate values of the detonator holes; a relative angle calculation part configured to calculate a relative angle between first and second detonator holes; and a blasting pattern coordinate conversion part configured to correct angles of the remaining detonator holes by reflecting the relative angle between the first and second detonator holes, and to provide converted blasting pattern coordinates that are obtained such that latitude and longitude coordinates of the detonator holes are converted based on the corrected angles.

A device for providing a converted blasting pattern coordinate, the device comprising:

a distance difference calculation part configured to preset any one of detonator holes displayed on coordinates of a blasting pattern as a reference point, and to calculate each distance difference between a X-coordinate of the detonator hole preset as the reference point (the reference detonator hole) and X-coordinates of remaining detonator holes and each distance difference between a Y-coordinate of the reference detonator hole and Y-coordinates of the remaining detonator holes;
a polar coordinate value derivation part configured to derive polar coordinate values of the detonator holes by designating the reference detonator hole as references of polar coordinates;
a relative angle calculation part configured to calculate a relative angle between a first detonator hole and a second detonator hole among the remaining detonator holes other than the reference detonator hole on the basis of latitude and longitude coordinate values and polar coordinate values between the first detonator hole and the second detonator hole;
and
a blasting pattern coordinate conversion part configured to correct angles of the remaining detonator holes by reflecting the calculated relative angle between the first detonator hole and the second detonator hole, and to provide blasting pattern coordinates by converting the detonator holes in form of latitude and longitude coordinates on the basis of the corrected angles.
