    • A system for collecting dust during drilling operations in a mine with a roof drill machine is described herein. The system consists of a mobile roof drilling machine having a conical shaped dust-collecting bowl adjacent to the surface being drilled. It is provided with annular space between the drill and the conical dust-collecting system to allow the drill to be injected into the roof of the mine. The system has a strong suction mechanism tangentially associated on each side of the dust-collecting system so as to provide a swirling motion of the falling dust particles.
    • 这里描述了一种用于在具有屋顶钻机的矿井中的钻井操作期间收集灰尘的系统。 该系统由移动屋顶钻机组成,其具有邻近被钻孔表面的锥形集尘碗。 它在钻机和锥形集尘系统之间设置有环形空间,以允许钻头注入矿山的屋顶。 该系统具有与集尘系统的每一侧切向相关的强抽吸机构,以提供落下的灰尘颗粒的旋转运动。
