Applications:
1. Construction drilling of the projects e.g. prospection,
geotechnical investigation, railway, road, port, bridge, water
conservancy and hydropower, tunnel, well, industrial and civil
construction;
2. Coal mining exploration, Or exploration;
3. Small hole diameter water well drilling.
Features:
1. Low cost, high efficency, resonable price
2. The best character is high rotation speed and it is applicable to core drilling with small-caliber diamond drill bit.
3. The complete hydraulic chuck and vertical spindle.
4. No exposure of bevel gear for the case opening, which enables the accuracy and reliability of the falling-in of gears, free from any pollution and with a long service life.
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.
