Zhao, MingChun from CsDrill is the world's top 2% scientists in 2022, China's first self-developed down-the-hole reverse circulation drill was successfully developed by his team. Make exploration sampling, drilling wells, mine blasting holes and other projects more efficient and energy-saving.
The down-the-hole reverse circulation drill we developed has solved two major problems in the world. The first is that when the borehole meets water, the slag is discharged into a wet mass and the inner pipe is blocked. In the video, you can see that despite the water, our slag discharge is dry and very smooth. Second, less slag discharge. In the video, you can see that our slag discharge is very large, which really achieves energy saving and efficiency.
