Summary:To solve a problem in which a rock drilling machine, a rock drilling rig, and a sensing device that measures physical features in rock drilling fail due to impact pulses of a drilling tool.SOLUTION: A rock drilling machine 6 comprises one or more sensing devices 19 arranged in connection with a bendable detection cord 20. The detection code 20 is sent to a flushing passage 15 of a drilling tool 8 via a feed passage 21.SELECTED DRAWING: Figure 3 【課題】削岩機、削岩リグ、および削岩中の物理的なフィーチャ（特徴）を測定する検知デバイスが、掘削工具の衝撃パルスによって故障する。【解決手段】削岩機６は、屈曲可能検知コード２０と接続状態で配置される１つまたは複数の検知デバイス１９を備える。検知コード２０は、フィード通路２１を介して掘削工具８のフラッシング通路１５に送られる。【選択図】図３
