摘要： A roof bit drill has a central shaft with a front end and a back end. The drill also has a base secured about the central shaft proximate to the front end, wherein the base has clearance channels extending axially therethrough. At least one cutting element is arranged on the base in a convex cutting pattern to permit loosened material to be evacuated. The roof bit drill may further include a drill depth locator to identify when the drill has been advanced within a mine roof to a predetermined depth. A method for using the roof drill bit is also disclosed herein.
摘要翻译：屋顶钻头具有具有前端和后端的中心轴。钻头还具有围绕中心轴固定的底座，靠近前端，其中基座具有轴向延伸穿过其中的间隙通道。至少一个切割元件以凸形切割图案布置在基部上，以允许松动的材料被抽真空。屋顶钻头钻头还可以包括钻头深度定位器，用于识别钻机在矿井顶部内的预定深度。本文还公开了使用屋顶钻头的方法。

摘要： A mine roof and rib support device comprising a support member, a roof support arm, a rib support arm, a bearing plate and a mine roof bolt. The roof support arm is provided at an angle to the rib support arm and comprises at least one aperture therethrough. The bearing plate comprises an upper edge and a lower edge and a through-hole defined therethrough. The upper and lower edges of the bearing plate can be positioned in abutment with the roof and rib support arms, respectively, with the through-hole being aligned with the aperture through the support member. The mine roof bolt extends through the through-hole of the bearing plate and the aperture of the roof support arm, thereby pressing the bearing plate against the support member. The upper edge exerts a force against the roof support arm and the lower edge exerts a force against the rib support arm.
摘要翻译：一种矿顶和肋支撑装置，包括支撑构件，屋顶支撑臂，肋支撑臂，支承板和矿顶螺栓。屋顶支撑臂设置成与肋支撑臂成一定角度，并且包括穿过其中的至少一个孔。轴承板包括上边缘和下边缘以及通过其定义的通孔。支承板的上边缘和下边缘可以分别定位成与屋顶和肋支撑臂邻接，其中通孔通过支撑构件与孔对齐。矿山屋顶螺栓延伸穿过支承板的通孔和车顶支撑臂的孔，从而将支承板压靠在支撑构件上。上边缘对屋顶支撑臂施加力，下边缘对肋支撑臂施加力。
