drill bits for mining

D Miningwell down-the-hole hammer drill bits are made of carbide inserts and steel. Widely used in water well drilling and protection of hard rock formations. In the past 20 years, we have exported dth hammers bits to many countries with good feedback. You are welcome to contact us if you need. We can supply all series of drilling equipment and drilling tools.

The cofferdam project is a large-aperture pile hole construction plan. 1000mm and 1200mm diameter casings need to be inserted into the rock formation for 5-6 meters, the total depth of the pile holes is 25-30 meters, 300 piles with a diameter of 1200mm, and 280 piles with a diameter of 1000mm. This solution is expected to allow the port to obtain a load capacity of 500,000 tons, thereby increasing the throughput of the Chulai port.
