  • 3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm. 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. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards

    The tableau, a term derived from the French word for picture or scene, holds a profound significance in both the art world and societal expression. Whether in the context of a painted canvas, a theatrical performance, or a frozen moment in photography, the tableau serves as a powerful medium for storytelling and reflection. This article explores the multifaceted nature of the tableau, its historical roots, and its impact on contemporary culture.

    Second, the use and characteristics of the drilling rig:
    1). Use:
    Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
    2). Features:
    1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.

    Gravel pumps are specialized centrifugal pumps that are capable of handling large particles and volumes of liquid mixed with solid materials. These pumps are essential in applications such as dredging, quarry operations, and the transfer of materials in concrete production. The unique design of gravel pumps allows them to operate effectively in harsh conditions, making them indispensable in industries that require robust and reliable equipment.

    The applications of mining slurry pumps are diverse. Their primary function is to transfer slurries from the point of extraction to processing facilities. In this stage, the slurry contains valuable minerals that need to be refined and extracted. Slurry pumps are also crucial in the dewatering process, where the goal is to remove excess water from extracted materials. This not only improves the efficiency of material handling but also protects the environment by reducing the risk of contaminated water discharge.
