Description
TECHNICAL FIELD

The present disclosure relates to a device and a method for providing a converted blasting pattern coordinate. More particularly, the present disclosure relates to a device and a method for providing a converted blasting pattern coordinate, wherein a relative angle between a first detonator hole and a second detonator hole among the remaining detonator holes other than a detonator hole preset as a reference point on the basis of latitude and longitude coordinate values and polar coordinate values between the first detonator hole and the second detonator hole is calculated, and angles of the remaining detonator holes are corrected by reflecting the calculated relative angle between the first detonator hole and the second detonator hole, thereby providing blasting pattern coordinates generated by converting the detonator holes into the form of latitude and longitude coordinates on the basis of the corrected angles.

BACKGROUND ART

The blasting operation is excellent in economy compared to other construction methods, and has been widely used even today.

A method using a conventional standard blasting pattern diagram, which is designed for each grade of rock mass with an emphasis on blasting efficiency, has been mainly used. The blasting pattern diagram actually used in the field has been applied such that a field manager of the blasting operation corrects the standard blasting pattern diagram on the basis of personal experience. In this case, the correction is dependent on the personal abilities or experience of the field manager, and when the objective test for the correction of the blasting pattern diagram cannot be made, the blasting pattern cannot be corrected properly and quickly.

Furthermore, since blasting pattern coordinates of the detonator hole provided in the blasting pattern diagram are indicated in the form of rectangular coordinates, it is difficult for the operator to determine an actual position and angle of a detonator hole.

In S100, the blasting pattern coordinates are configured in the form of rectangular coordinates as shown in FIG. 5.

Distances between the X-coordinate and Y-coordinate of the reference detonator hole and the X-coordinates and the Y-coordinates of the remaining detonator holes are calculated in S100.

Next, the reference detonator hole is designated as the reference of the polar coordinates, and the polar coordinate values of the detonator holes are derived (S200).

In S200, the polar coordinate values including at least one of the distance and the angle of each of the detonator holes are derived, as shown in FIG. 6.

Next, the relative angle between the first detonator hole and the second detonator hole among the remaining detonator holes other than the reference detonator hole is derived on the basis of the latitude and longitude coordinate values and the polar coordinate values between the first detonator hole and the second detonator hole (S300).

In S300, the first detonator hole and the second detonator hole are arbitrarily designated among the remaining detonator holes, and the latitude and longitude coordinate values of the first detonator hole and the second detonator hole are derived by collecting the GPS location information of the first detonator hole and the second detonator hole. Then, the first angles of the first detonator hole and the second detonator hole are calculated from the derived latitude and longitude coordinate values of the first detonator hole and the second detonator hole, and the second angles of the first detonator hole and the second detonator hole are calculated from the derived polar coordinate values of the first detonator hole and the second detonator hole. The first angles and the second angles are compared to each other to calculate the relative angle between the first detonator hole and the second detonator hole, and the correction angle value is derived on the basis of the derived relative angle, as shown in FIG. 7.

Next, the angles of the remaining detonator holes are corrected by reflecting the calculated relative angle between the first detonator hole and the second detonator hole. On the basis of the corrected angles, the blasting pattern coordinates are provided in a state in which the detonator holes are converted in the form of the latitude and longitude coordinates (S400).

In S400, the angles of the detonator holes are corrected by the correction angle value derived on the basis of the derived relative angle. The latitude and longitude coordinate values of the detonator holes are derived on the basis of the corrected angles of the detonator holes and the calculated distance differences between the X-coordinates of the reference detonator hole and the remaining detonator holes and the calculated distance differences between the Y-coordinates of the reference detonator hole and the remaining detonator holes.
