The present invention is directed to a boom supporting a slide assembly (1001). The slide assembly (1001) includes a guide track (1002), a drill (1006), and a stemming member (1005) for use in a small charge blasting. The drill (1006) is initially moved along the guide track (1002), and the stemming member (1005) is moved along the guide track (1002) and placed in the drill hole. After the stemming member (1005) fractures the rock, the stemming member (1005) is retracted along the guide track (1002) and the steps repeated to break new material. The stemming member (1005) has a breech and barrel that are located in the holes. The breech is either side- or front-discharging.
La présente invention se rapporte à une flèche supportant un ensemble coulissant (1001). Ce dernier comporte une piste de guidage (1002), un foret (1006), et un élément générateur de gaz (1005) destiné à l'abattage à l'explosif à faible charge. Le foret (1006) est déplacé initialement le long de la piste de guidage (1002) et l'élément générateur de gaz (1005) est déplacé le long de la piste de guidage (1002) et placé dans le trou de mine. Une fois que l'élément générateur de gaz (1005) a permis de fracturer la roche, il est rétracté le long de la piste de guidage (1002) et les étapes sont répétées de manière à briser plus de matière. L'élément générateur de gaz (1005) comporte une culasse et un canon qui sont placés dans les trous. La culasse est à décharge latérale ou frontale.
