As technology progressed, coal mine tools underwent a transformation. The introduction of pneumatic machines in the 19th century revolutionized coal extraction. Devices like the pneumatic pick, powered by compressed air, significantly increased the speed and efficiency of coal cutting. This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations

Lock sewing, often referred to as “lock stitch sewing,” is a technique that utilizes two threads—one from the needle and the other from the bobbin—to create a secure stitch. The stitches interlock at the seam, making it less prone to unraveling. This method is widely used in both industrial and home sewing machines because of its efficiency and the neat finish it provides.
