    • An apparatus for bolting the roof of an underground mine is disclosed comprising a mobile frame, a boom extending from the frame and a housing provided at the end of the frame. The housing supports an upwardly extending stinger, a drilling mechanism including a drill centralizer having a central bore therethrough and a passageway in communication with the central bore, a device for delivering a container of roof bolting anchoring media through the passageway and through the drill centralizer and into a drilled hole, a device for indexing a roof bolt into alignment with the drilled hole and a spinner for driving the roof bolt into the drilled hole. The present invention also provides a method for bolting the roof of an underground mine comprising the steps of stinging a housing against the roof of the mine, moving a drill centralizer into communication with the roof and drilling a hole in the roof. Without retracting the drill centralizer from communication with the roof, a container of roof bolt anchoring media is delivered through the centralizer and into the drilled hole. The drill centralizer is thereafter retracted and the housing is moved to align a roof bolt with a drilled hole. Then the roof bolt is driven into the drilled hole and the bolt anchoring media sets around the bolt.
    • 公开了一种用于螺栓连接地下矿井的屋顶的装置,包括一个可移动框架,一个从框架延伸的起重臂和一个设在框架末端的壳体。 壳体支撑向上延伸的托管架,钻孔机构包括具有穿过其中心孔的钻孔定心器和与中心孔连通的通道,用于通过通道并通过钻头中心器输送顶部螺栓锚定介质的容器的装置,以及 钻入钻孔中,用于将屋顶螺栓分配到与钻孔对准的装置和用于将屋顶螺栓驱动到钻孔中的旋转器。 本发明还提供了一种用于将地下矿井的屋顶螺栓固定的方法,其特征在于包括以下步骤:将壳体靠在矿井的屋顶上,使钻孔扶正器与屋顶相通,并在屋顶上钻一个孔。 在不缩回钻头扶正器与屋顶连通的情况下,将屋顶螺栓锚固介质的容器通过扶正器输送到钻孔中。 然后,钻孔扶正器被缩回并且壳体被移动以使屋顶螺栓与钻孔对齐。 然后将屋顶螺栓驱动到钻孔中,螺栓锚定介质围绕螺栓设置。
