Hydraulic drilling rigs play an essential and irreplaceable role in the domains of metal ore and coal exploration.

In metal ore exploration, these rigs, owing to their remarkable performance, have emerged as the linchpin of exploration activities. They can adeptly handle a diverse range of complex geological settings. Be it the tough granite, quartzite, or the relatively fragmented ore vein strata, they are capable of conducting drilling operations with high efficiency. Their precise drilling capabilities guarantee the attainment of top-notch core samples. These samples are of utmost significance as they enable accurate determination of crucial information such as the specific types of metal ores, their grades, the intricate structures of the ores, and the directions of ore veins. For instance, during copper ore exploration, hydraulic drilling rigs can drill at precisely predetermined angles and depths. The core samples retrieved can vividly display the characteristics of the copper ores, the fluctuations in copper content, and the symbiotic associations with other minerals. Thereby, it furnishes the most direct and dependable foundation for geological experts to assess the reserve magnitude, the mining complexity, and the economic worth of copper ores.

In coal exploration, hydraulic drilling rigs likewise exhibit outstanding performance. They can function effectively under assorted topographical and geological circumstances, whether it's the exploration of coal seams in mountainous terrains or the detection of deep coalfields in plains. Through the drilling operations of these rigs, key parameters like the quantity of coal seams, their thicknesses, inclinations, and coal qualities can be meticulously ascertained. In certain large-scale coalfield exploration initiatives, multiple hydraulic drilling rigs can operate concurrently to expeditiously explore extensive areas and precisely map out the distribution of coal seams. This offers accurate data support for the rational planning of coal mining. Additionally, during the drilling process, hydraulic drilling rigs can also conduct preliminary examinations of safety-related indices such as the gas content in coal seams. This affords valuable references in advance for devising subsequent mining safety protocols and ensures the seamless progress of coal mining operations.
