Latest Patents

Angela holds a patent for a machine designed for mine roof support, specifically titled "Mine roof supporting." This invention features a roof pin-or-bolt setting machine that utilizes sonic energy to drive bolts, which can be of non-circular section or helical, into the roof of a coal mine. The machine operates by supplying energy through a bar that is set into sonic vibration in its bending mode. This creates a standing wave along the bar, allowing for effective bolt installation at specific positions known as anti-nodes. The continuous vertical force applied to the bar ensures that the bolt remains engaged with the roof under pressure, enhancing the stability of the mine structure.
