1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

  • There are several types of mining drill bits, each designed for specific tasks and geological conditions. The most common types include diamond core drill bits, tricone bits, PDC (polycrystalline diamond compact), and drag bits. Diamond core drill bits are used for drilling into hard rock formations, while tricone bits are versatile tools that can be used in a variety of geological conditions. PDC bits are ideal for drilling through abrasive formations, while drag bits are used for softer rock formations.

  • Zhai Jinguo, deputy general manager and vice president of Shanghai Chemical Institute, said:

  • Pultrusion is a continuous manufacturing process where reinforcement materials, primarily glass fibers, are pulled through a resin bath, then heated and formed into the desired shape.
