Social connections are another fundamental pillar in the framework of resilience. Humans are inherently social beings, and the support of friends, family, and community can provide a cushion during tough times. Engaging with others fosters a sense of belonging and purpose, which can give individuals the strength to overcome adversities. This network of support allows individuals to share their burdens and feel less isolated, making the challenges of life more manageable.

  • 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.

    The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

    In conclusion, spiral foraging offers a unique and sustainable approach to gathering wild edibles. By combining ecological understanding with a systematic method of exploration, foragers can cultivate a deeper appreciation for nature while minimizing their impact on the environment. This technique not only enhances the foraging experience but also promotes responsible practices that benefit both the gatherers and the ecosystems they inhabit. As we continue to seek sustainable food sources, methods like spiral foraging serve as valuable reminders of our interconnected relationship with the natural world.
