Shallow Coring Mining Exploration Core Drill Rig / Concrete Core Drilling Equipment

Shallow Coring Mining Exploration Core Drilling Rigs for Mining Exploration

Product Description:

The Jinzhou Shitan mining exploration core drilling rigs are made for the shallow coring from surface and in underground. The core diameter is customized and the hole depths up to 300m. Horizontal and vertical drilling is possible depending on the rig type and model. Ideal machine for the shallow coring, mining exploration special companies and mines.

Light and portable, the ST-300 geotechnical drill rig is perfect for low depth geotechnical activities, for coring, augering and down-the-hole hammering.
Easy-designed type mounted on a four-wheel drive vehicle or crawler to facilitate access to restricted areas. The simple yet robust design of the ST-300 is easy to maintain and is well adapted to very demanding drilling conditions.

Main Characteristics of ST-300:

1. There are more speed grade (8 grades), reasonable speed range and high torque while low speed. Max. torque is up to 3200 N•m (2358 lbf•ft). The core drill rig ST-300 is adapted on core drilling with tungalloy-carbid-tipped and diamond oil as well as engineering geology exploration, hydrology well drilling and basic pile engineering.

2. With large spindle I.D. 93mm (3.66 inch), the drill is fed with double hydraulic cylinders with much longer stroke up to 600mm (23.62 inch). With strong technological adaptability, the rig can be adapted on many field, especially on large diameter drill rod drilling, (upper part coring) extracting core with wire line. Thus it is more effective in improving drilling efficiency with less faulty in hole.

3. With powerful drilling capacity for the core drill rig, the rated drilling depth comes up to, 000m (39.37 inch) with 71mm (2.80 inch) wire-line coring drill rod.

4. Light in weight, and in fine dismount ability, the rig can be dismantled into ten parts easily; the biggest apparatus is in 300 kg (661.5 lb). The whole drill is in 2150kg (4741 lb), it can be moved easily especially in mountain area.

5. Clamped with Belleville spring and loosened with hydraulic cylinder, the hydraulic chuck is adopted with three-jaws self centering. It is in strong and steady clamping force.

6. This core drill rig is equipped with a water brake for steady and smooth deep hole drilling.

7. Supplying oil with a simplex gear pump, it is easy for installation and operation; lower in energy consumption and in low oil temperature of hydraulic system; the core drill rig is for sure in steady drilling. The hand-operated oil pump can be put in use to hoist the drilling tools in hole upon the power engine failing to operate.

8. With compact structure and reasonable layout, with all components exposed, and with non overlapped ones, it is convenient for maintenance.

9. With low center of gravity and long traveling distance up to 460mm (18.1 inch), the rig is reliable and stable in high speed drilling.

10. It is easy to get to know the conditions in hole with an ant vibration meter. Less in operating handles, the rig can be operated credibly and flexibly.

11. The core drilling rig can work steadily and securely in deep hole drilling

12. By operating with single or double gears, there is a low consumption of energy and a low temperature of hydraulic system oil.

13. In cases of the power out of order, the hand reeling oil pump may be used to hoist the drilling tools.

14. As for its structure, this core drill rig is compact and reasonable.

15. It is easy to master the hole condition with a long life anti-vibration instrument.
