  • 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.

    Importantly, the tableau fosters a moment of contemplation, serving as a bridge between the observer and the observed. It invites viewers to engage with the art, not merely as passive spectators but as active participants in the interpretive process. The stillness of the tableau often leads to introspection, prompting questions about the underlying narrative and its relevance to personal and societal contexts. This engagement encourages a deeper understanding of the complexities of human experience, facilitating a dialogue that transcends cultural and temporal boundaries.

  • Despite their many advantages, fiberglass reinforced pipes do have some limitations. They may be more expensive than traditional materials such as PVC or steel, and require specialized knowledge and equipment for installation. Additionally, while FRP pipes are generally resistant to most chemicals, they may not be suitable for all corrosive environments.
  • Settler groups often brought their own cultural values and traditions with them when they arrived in a new land. However, colonialism often led to the erosion of these cultures as settlers were forced to adopt the norms and values of the colonizing power. This process of assimilation was often accompanied by violence and repression, making it difficult for settlers to maintain their cultural identity.
