As a manufacturer specializing in the manufacturing of engineering rock drilling equipment, our focus is on developing reliable solutions for harsh underground environments. The YT28 pneumatic air leg rock drilling rig is specifically developed for this scenario, designed for those who control dust particle size and perform drilling operations in harsh environments, such as excavation work in close proximity to aquifers. This machine integrates a built-in wet drilling system, which can suppress dust generation from the source by directly guiding water flow through the drilling steel. The operator only needs to connect the drilling rig to the standard compressed air pipeline and water supply system; The system will then automatically mix the fluid without the need for complex adjustments. This setting can effectively reduce silica dust in the air, improve the visibility of workers, and significantly reduce the health risks caused by inhaling particulate matter. Of particular importance is the continuous flow of coolant, which can prevent the drill bit from overheating, especially when penetrating wet rock formations, ensuring sustained performance and reducing downtime caused by tool replacement.
Before and after using the S250 air leg rock drill (which shares core principles with the YT28), the working environment of mining and tunnel operation teams was vastly different. Traditionally, dry drilling under similar conditions generates dense dust clouds, obscuring the work site, accelerating mechanical wear, and posing serious respiratory health risks. Frequent maintenance intervals and extra caution are often required when working near sensitive hydrological structures. After using the S250 and YT28 air leg rock drills, the situation underwent a significant change. The mandatory water injection operation has completely changed the drilling process. The homework site environment should be kept clear to facilitate precise hole alignment and safer operation. The service life of drill steel is extended because water can significantly reduce friction and effectively dissipate heat accumulation. This directly brings measurable benefits: reducing the number of job interruptions, maintaining a stable progress rate, and creating a fundamentally healthier environment for personnel. Being able to actively protect the integrity of operators and surrounding geological structures while maintaining the highest drilling efficiency, making the rock drilling process more convenient.
YT28 is based on this mature wet drilling technology and designed specifically for the harsh conditions of groundwater pipeline construction. These projects, whether used for hydroelectric power generation, irrigation, or municipal supply, typically require tunnel construction through rock units saturated with groundwater. The challenge in engineering is twofold: to achieve the necessary permeability while strictly mitigating any interference that may cause pollution or structural damage. YT28 directly solved this problem. Its efficient impact mechanism provides strong impact force for rapid rock fragmentation, while water flushing solidifies the cut material into manageable mud, preventing loose debris from infiltrating the water channel. Compared with the dry substitution method, this method has better control effect, and the dry substitution scheme has the risk of surrounding rock cracking due to thermal stress.In addition, the balanced design of the drilling rig and adjustable air legs provide stable positioning on frequently wet or uneven tunnel surfaces, allowing operators to control precise drilling modes.
For contractors, the core of the value proposition is predictable and uninterrupted progress. Reducing dust means reducing the wear and tear of auxiliary equipment such as ventilation filters, while increasing tool life reduces consumption costs. Ultimately, YT28 can achieve a smoother, safer, and more economical excavation process, ensuring that critical water infrastructure projects are completed on time without sacrificing safety or environmental protection. It is not just about drilling rocks, it also manages the entire drilling ecosystem.
