Product Description
The TAIYE-660+-DTH Hydraulic Submarine Drilling Machine is designed for 90–130 mm blast hole drilling in surface mining, quarrying and infrastructure projects. It combines the hydraulic drilling system, diesel engine and air compressor in one machine, eliminating the need to transport a separate compressor during routine relocation.
The series includes two models: the 660H+ for medium-hard rock formations and the 660M+ for softer formations such as those encountered in open-pit coal mining. Both models use a 206 kW Yuchai diesel engine, with different rotation and air compressor configurations to suit their intended conditions.

Both models offer a 90–130 mm drilling range, but their rotation systems and compressor outputs are different. Selecting the version according to rock conditions and drilling requirements is more useful than comparing engine power alone.
| Selection Criteria | 660H+ | 660M+ |
|---|---|---|
| Primary Rock Conditions | Medium-hard rock | Soft rock and coal mine formations |
| Typical Applications | Quarries, metal mines, hydropower projects | Open-pit coal mining |
| Rotation Speed | 0–130 rpm | 0–180 rpm |
| Maximum Rotary Torque | 2,950 Nm | 1,750 Nm |
| Air Delivery | 16 m³/min | 15 m³/min |
| Air Pressure | 20 bar | 18 bar |
| Standard Drill Pipe | 76 × 4,000 mm | 76 × 3,000 mm |
The 660H+ provides 2,950 Nm of rotary torque and a 16 m³/min compressor operating at 20 bar. Its configuration is intended for medium-hard formations encountered in quarrying, metal mining and hydropower construction.
● Select the 660H+ when your project requires 90–130 mm blast holes in medium-hard rock and its torque and air supply match the selected DTH hammer.
The 660M+ is configured for softer rock conditions, particularly open-pit coal mining. It offers a rotation speed of up to 180 rpm, with a 15 m³/min compressor operating at 18 bar.
● Select the 660M+ when working in suitable soft formations and when its rotation speed, torque and compressor capacity meet the drilling requirements.
Final model selection should account for actual rock conditions, DTH hammer size, required depth and site operating conditions.
The engine, hydraulic pump, air compressor and radiator are arranged longitudinally with direct connections. This compact layout keeps the power and air supply systems on the drilling rig rather than requiring a separate compressor vehicle.
Both versions use the Yuchai YCA08280-T301 turbocharged diesel engine, rated at 206 kW at 2,200 rpm. The common engine platform simplifies engine-related specification comparison between the two models.
The intake system combines a cyclone pre-filter, coarse filter and fine filter. The three filtration stages help limit dust entering the engine and compressor in dusty surface drilling environments.
Both models have a listed 6+1 drill rod configuration. The 660H+ uses 76 × 4,000 mm rods, while the standard 660M+ uses 76 × 3,000 mm rods, with a 4,000 mm specification also listed by Taiye.
The TAIYE-660+ is a surface DTH drilling rig intended primarily for projects requiring 90–130 mm holes. The two available configurations address different rock conditions and project requirements.
● The 660H+ is suitable for evaluating medium-hard rock drilling requirements in limestone and other quarry operations, subject to site geology and hammer selection.
● The 660M+ is designed for softer formations encountered in open-pit coal mining, with a rotation and air supply configuration intended for these operating conditions.
● The 660H+ can be considered for medium-hard formations in surface metal mining projects requiring holes within its specified diameter range.
● The 660H+ can be used for suitable rock drilling and blasting work in hydropower construction projects where the required hole diameter and geological conditions match its specifications.
Compare the standard published specifications of the 660H+ and 660M+ before selecting the appropriate hydraulic DTH drilling rig.

Note: The published 660M+ specifications also list a 4,670 mm feed rail stroke configuration. Confirm the selected drill pipe and feed rail arrangement when ordering.
If your drilling requirements extend beyond the 90–130 mm range, Taiye also offers the TAIYE-670+ Integrated DTH Drilling Rig. It has a wider published hole diameter range and an automatic rod changing system.

The 660H+ is configured for medium-hard rock, with 2,950 Nm of rotary torque and a 20 bar compressor. The 660M+ is intended for softer formations, including open-pit coal mining, and provides up to 180 rpm rotation speed with an 18 bar compressor.
No separate compressor is required for its standard integrated configuration. The 660H+ has a listed output of 16 m³/min at 20 bar, while the 660M+ provides 15 m³/min at 18 bar.
Both versions have a published drilling diameter range of 90–130 mm. The appropriate DTH hammer and drill bit should be selected according to the target diameter and rock conditions.
The 660H+ is intended for medium-hard formations, including quarry applications. Provide rock information, required hole diameter and drilling depth so Taiye can check whether its torque, compressor and rod configuration meet your needs.
Please specify the intended application, rock conditions, hole diameter, required depth, estimated number of holes and project location. Taiye can use these details to discuss the appropriate model and configuration.
