DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

Heavy Slurry Pumps from China An Overview

Understanding Heavy Slurry Pumps

1. Offshore Oil and Gas Exploration In the oil and gas industry, submarine hammer drilling is crucial for the installation of subsea pipelines and wellheads. The ability to efficiently penetrate the seabed allows for the secure placement of infrastructure that can transport hydrocarbons from extraction points to processing facilities.

- Durability Look for pumps made of corrosion-resistant materials, especially if they will be exposed to harsh environments which can cause damage over time.

2. Road Work Ideal for applications such as road repair and maintenance, where heavy equipment is needed.
