    Abstract: A hydraulic hammering device is capable of sufficiently transmitting blow energy to bedrock while further strengthening cushioning action and suppressing damage to equipment. The device includes a pushing piston disposed behind a transmission member and having a smaller propulsive force than that of a main body, a damping piston positioned behind the pushing piston to slide reciprocally forwards and backwards and having a greater propulsive force than that of the main body, a direction-restrictor in a high-pressure circuit between pushing and damping chambers, to which hydraulic fluid is supplied for providing the pistons with propulsive forces, and a fluid supply source. The direction-restrictor restricts an outflow from the chambers side to the fluid supply source side while allowing fluid inflow from the fluid supply source side to the chambers and the pushing chamber sides. A throttle in a drain circuit discharges leaked fluid from a sliding contact location to a tank.

    Abstract: A continuous mining machine having a cutter frame with two rotary boring heads mounted on this frame for rotation about axes extending longitudinally of the machine. Each boring head has a plurality of radially extending rotor arms which carry and support cutter bits on the front thereof. A pair of reciprocating pole devices are mounted in each of the rotor arms for movement in the radial direction of the arm. A number of link members are each pivotally connected at opposite ends thereof to respective pair of the pole devices and additional cutter bits are mounted on the link members. There is also a cam mechanism for reciprocating each pair of pole devices as the boring heads are rotated. The cam mechanism causes each pair of pole devices to be pushed radially outwardly at each of the four corners distributed about a circular hole cut by the respective boring head in such a manner that the resulting hole bored by the machine is generally rectangular. Preferably, each pair of pole devices has rollers mounted thereon and each rotor arm has tracks mounted therein, on which the rollers run. The preferred mining machine includes a mobile frame with a longitudinal conveyor mounted on this frame having a forwardly open throat adjacent floor level.

    Abstract: An excavating machine having a cutter head which is provided with both reciprocating impact hammers and a static pick. The impact hammers are mounted on either side of the static pick so as to flank this, and the tip of this can be extended or retracted relative to the tips of the hammers. The ripper pick can thus scarf out a mound of earth left between the two impact hammers, or can be extended to cut a channel into which the impact hammers then drive the adjacent material. The impact hammers can be tilted relative to the axis of the ripper pick so that their tips either precede or follow that of the pick as they are moved across the working face. The cutter assembly may be mounted to a tracked vehicle so as to extend forwardly from this for continuous mining, or laterally from this for long wall mining.

    Abstract translation: 一种具有切割头的挖掘机，该切割头设有往复式撞击锤和静态镐。 撞击锤安装在静态拾音器的两侧，以便侧面，并且其尖端可以相对于锤的尖端延伸或缩回。 因此，裂土器拾取器可以在两个冲击锤之间划出一块留下的土堆，或者可以延伸以切割冲击锤然后驱动相邻材料的通道。 冲击锤相对于松土机的轴线可以倾斜，使得它们的尖端可以在拾取器的前面或之后移动到工作面上。 切割器组件可以安装到跟踪的车辆上，从而从其向前延伸用于连续采矿，或者横向从其延伸用于长墙开采。

    Abstract: An ore dislodging mechanism and a method for extracting ore from a vein which greatly increase productivity and reduce health hazards when compared with previous devices and methods. The ore dislodging mechanism includes a chisel bar which is forced into the ore vein to dislodge ore therefrom, and an elevated means for raising the chisel bar in a substantially vertical manner so that each extraction made by the chisel bar is parallel with previous extractions. Side cutters extend vertical kerfs along the sides of the chisel bar and the chisel bar breaks down the coal between the kerfs.The method includes the steps of undercutting a vein of ore, extending at least one vertical relief cut upwardly from the undercut, forcing a chisel bar into the vein of ore, thereby dislodging the ore therefrom, and raising the means for cutting the relief cuts and the chisel bar mechanism to make progressively higher extractions parallel with lower extractions.

    Abstract: A mining machine having a rotary mining head which comprises an elongated support carrying a plurality of laterally spaced, rotatable cutter support drums fixed against lateral movement and rotatable end cutter support drums laterally movable to vary the length of the mining head by separate pistons in cylinder means contained in the support. The first mentioned drums carry cutter bits arranged to cut along the therebetween spaces thereby avoiding the necessity for cutter chains or other auxiliary cutting or breaking means therebetween; and the drums are rotatably driven by a pair of drive motors through clutchless interconnecting means including intermeshing gears in the mining head on non-parallel axes.
