ST 350 Water Well Boring Machine Brief Introduction:
The birth and development of pneumatic water well drilling rig represents a major revolution in drilling technology. This innovative approach has transformed traditional cutting and grinding methods for rock breaking, significantly improving drilling efficiency and adaptability to hard and complex geological formations. Its remarkable technical and economic benefits are recognized as a hallmark of modern drilling technology, valued by the drilling industry worldwide.
Pneumatic DTH (Down-The-Hole) hammer drilling originated from applications in drilling blast holes, water well foundation rock holes, and geological exploration. To expand its utility, researchers globally have continuously improved the design and working performance of DTH hammers to meet diverse engineering requirements.

- High slag discharge wind speed ensures clean hole bottom with no secondary crushing
- No liquid column pressure improves hole bottom crushing conditions without groundwater interference
- High-frequency impact drilling reduces hole inclination effects on rock or inclined strata, improving drilling verticality and reducing wall collapse
- Requires significantly less Weight on Bit (WOB) and torque compared to rotary well drilling rigs
- Excellent adaptability to work under various complex rock strata, including aquifers
- Simple structure with convenient use and maintenance
