XY-1 Core Drill Rig Characteristics
1. With hydraulic automatic feeding device, elevated drilling efficiency.
2. The holding mechanism with upper spherical jaws is used as substitute for chuck. The rod can be replaced without shutdown.
3. Centralized handles, easy operation, safe and reliable.
4. The drilling rig, pump and diesel engine are installed on a common base frame in order to have a compact structure and occupy small field area.
5. Light weight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.
XY-1 Core Drill Rig Drilling method of pebble layer
1 conventional drilling methods and characteristics
At present, conventional drilling methods such as diamond drilling, clean water flushing, pipe reaming and mud circulation are generally used, while rotary drilling, dry drilling, pipe following, percussion, steel wire drill and other coring methods are used for core mining.
The disadvantages of these methods in drilling pebble layer are large drilling load, many accidents in the hole, low drilling efficiency and poor coring quality.
2. Drilling method and characteristics of diamond drilling tool combined with vegetable glue washing fluid
In order to meet the requirements of drilling in various hard and fragile formations, a series of single acting double barrel diamond drilling tools combined with vegetable gum washing fluid have been specially developed. It is also a relatively advanced method of drilling progressive cores in such formations at present. This method is a drilling process using vegetable gum as washing fluid and diamond as drilling tool.
The main characteristics of this process are small rotary resistance, high drilling efficiency, good coring quality, and strong ability to discharge sand and carry rock powder.
