    • An apparatus for use in connection using a drill having a drilling element for forming a borehole in a face of a mine passage includes a drill guide for engaging the drilling element while permitting the drilling element to move toward the face for forming the borehole. The drill guide includes a keeper for keeping the drilling element in a desired position, which keeper is biased for pivoting movement upon the application of a manual force between an active position for capturing the drilling element and a retracted position for releasing the drilling element. A low profile drill guide is also disclosed, as is a guard for a drill guide, and also related methods.
    • 一种用于使用具有用于在矿井通道的表面中形成钻孔的钻孔元件的钻头连接的装置,包括用于接合钻孔元件的钻子引导件,同时允许钻孔元件朝向用于形成钻孔的表面移动。 钻子引导器包括用于将钻孔元件保持在期望位置的保持器,当在用于捕获钻孔元件的活动位置和用于释放钻孔元件的缩回位置之间施加手动力时,该保持器被偏置以用于枢转运动。 还公开了一种小型钻孔引导器,以及用于钻孔引导器的防护件以及相关方法。
