SLIDE ASSEMBLY HAVING RETRACTABLE GAS-GENERATOR APPARATUS

摘要

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 stemmi ng 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 memb er (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.
