摘要： A drill string comprises a mechanical drill bit and a ram accelerator with a launch tube proximate to the mechanical drill bit. A projectile accelerated by the ram accelerator exits the mechanical drill bit through an orifice and impacts a geologic formation. The impact weakens a portion of the formation, enabling the drill bit to penetrate the weakened portion more easily. An endcap may be used to prevent outside material from entering the ram accelerator. The projectile may pass through or otherwise displace the endcap during operation. The launch tube may be positioned at an angle relative to the drill bit such that projectiles impact and weaken the formation on a particular side. Contact between the drill bit and the formation may direct the drill bit toward the weakened side, enabling the ram accelerator to be used to steer the drill bit.
摘要翻译：钻柱包括机械钻头和具有接近机械钻头的发射管的冲头加速器。被撞锤加速器加速的抛射体通过孔口离开机械钻头并撞击地质构造。冲击削弱了地层的一部分，使钻头更容易穿透弱化部分。端盖可用于防止外部材料进入冲头加速器。操作期间，射弹可以穿过或以其他方式移动端盖。发射管可以相对于钻头成一定角度定位，使得射弹撞击并削弱特定侧上的地层。钻头与地层之间的接触可以将钻头引向弱化侧，使得油缸加速器能够用于转向钻头。

摘要： One aspect of the invention concerns a pneumatic rock drill (10) having a cylinder (18), a least one exhaust opening (30) from the cylinder through which air is exhausted and a muffler (42) which extends around the cylinder and over the exhaust opening. The muffler has a muffler casing (44) which surrounds the cylinder and includes casing parts (46, 48) assembled together around the cylinder. The4 muffler casing defines a muffler space (70) extending around the cylinder with the exhaust opening venting into an upper part of the muffler space towards its rear end. There is a series of spaced apart exhaust ports (80) venting downwardly from a front end of the muffler space through the muffler casing. There is also a baffle structure (72) located in the upper part of the muffler space between the exhaust opening and the exhaust ports. This structure includes spaced apart, perforated baffle plates (76) through which air venting into the muffler space through the exhaust opening must pass en route to the exhaust ports. Another aspect of the invention concerns the muffler itself.

The shovel includes a motor configured to rotate the auger bit and a portable power source configured to power the motor. The shovel includes an input/output (I/O) device and a controller to control rotation of the auger bit. The shovel has a handle and a shovel portion. In one example, the power source is integrated into the handle, and in another example, the power source is detachably coupled to the handle. The shovel has a gearbox coupled to the motor. The shovel portion includes a blade positioned proximal to the auger bit to retain debris from the auger bit. The auger bit has a flute that is partially covered by the blade, and the blade defines a discharge opening configured to discharge at least some of the debris.
