摘要： A rock bolt in the form of a steel tube (11) is placed in a borehole in rock and is then expanded against the rock by means of an expandable body (15) inside it. The expandable body (15) comprises a rubber hose which is temporarily pressurized to a pressure that is usually 50-100 MPa so that the bolt anchors in the borehole. The expandable body (15) is part of a mounting tool and it is withdrawn immediately when depressurized.

摘要： A rock bolt comprises an inflatable tube (11) which has a deep longitudinal depression (12). A wire coil (20) is mounted on the tube before the bolt is inserted in the borehole. When pressurized by high pressure water the tube (11) expands and clamps the coil (20) between itself and the borehole and the tube (11) is thereby permanently anchored in the borehole. The depression (12) develops during the expansion but the coil (20) prevents full expansion of the tube (11).
摘要翻译：岩石螺栓包括具有深纵向凹陷（12）的可充气管（11）。在将螺栓插入钻孔之前，将线圈（20）安装在管上。当通过高压水加压时，管（11）在其与钻孔之间膨胀并夹紧线圈（20），并且管（11）由此永久地锚定在钻孔中。凹陷（12）在膨胀期间形成，但线圈（20）防止管（11）的完全膨胀。

摘要： A rock drill boom structure comprises a support means, an elongated boom swingably carried by the support means and a feed beam on which a rock drill is mountable so as to be power displaceable therealong, the feed beam being carried by one end of the boom. The support means includes an elongated hollow guide means of substantially less longitudinal length than the boom and in which the boom is slidably received to project through both ends of the guide means, the boom being arrestable in the guide means, a rotatable member on which the guide means is pivotably mounted for pivotable movement about an axis transverse to the axis of rotation of the rotatable member, first power means for pivoting the guide means and second power means for rotating the rotatable member. The rotatable member 19 is preferably disc-shaped and has an aperture therein through which the power lines of the rock drill are drawn.
摘要翻译：岩石钻杆结构包括支撑装置，由支撑装置可摆动地承载的细长吊杆和可安装凿岩机的进给梁，以便能够沿着其移动，进给梁由吊杆的一端承载。支撑装置包括细长的中空引导装置，其长度比起重臂小得多，并且其中吊臂可滑动地被容纳以伸出通过引导装置的两端，悬臂可阻止在导向装置中，可旋转构件引导装置可枢转地安装成可围绕横向于可旋转构件的旋转轴线的轴线枢转运动，用于枢转引导装置的第一动力装置和用于旋转可旋转构件的第二动力装置。可旋转构件19优选地是圆盘形的并且具有孔，凿岩机的动力线通过该孔被拉出。
