Title:
岩洞掘削用穿孔パターンの設計
Document Type and Number:
Japanese Patent JP5167269
Kind Code:
B2
Abstract:
The invention relates to a method and a software product for designing a drilling pattern for excavating a rock cavern. The invention further relates to a rock-drilling rig, in whose control unit the software product and the method are executable. During designing of the drilling pattern, drill hole bottom locations are placed at a blast plane at the bottom of a round. A drilling pattern design program determines the missing properties of the drill holes viewed from the bottom of the round towards a navigation plane. The program is able to determine a starting location for a drill hole based on the location and the direction of the bottom. The program also performs blasting calculation on the drill holes positioned.
