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.

To practice spiral foraging effectively, it is crucial to have a solid understanding of local flora and fauna. Foragers should familiarize themselves with the edible plants in their region, as well as any potential lookalikes that could be harmful if consumed. Identification skills can be honed through field guides or by joining local foraging groups where experienced foragers can share their knowledge. This learning journey not only enriches the foraging experience but also fosters a sense of community among those who share a passion for sustainable practices.
