Overburden Casing Drilling" (OCD) is a drilling technique used to advance casing while drilling through challenging formations such as loose or unstable ground, gravel, cobbles, boulders, and bedrock. The Overburden Casing Drilling Bit (OCD bit) is a specialized tool used in this drilling process.
MING Ring Bit System can be used for drilling operations such as foundation building, piling construction, water well and geothermal drilling, tunneling, and horizontal drilling in all types of ground conditions.

FAQ:
1. What is drill casing in mining?
In underground mining, steel casing or steel pipe is used to line holes that have been bored or drilled for rising mains water, utility lines and paste fill, protecting the contents from damage and loss into open voids or broken ground.
2. What distinguishes drill pipe from casing?
The drill pipe frequently rotates the drill bit, which cuts into the rock until it reaches the deposits. In every wellbore, the first step is to drill with drill tubing. Casing refers to the tubing that is installed inside the drilled well to sustain and protect the well stream, also known as the casing pipe.
3. Where does excess material from digging operations go?
Overburden is employed for field contouring, reprocessing, and as a building and road construction aggregate. Clay, tiles, glass, and concrete are all produced using recycled mine waste. After being treated, mine water is used as a coolant, to suppress dust and particulates, and in agriculture and industry.
