UNDERGROUND DRILLING
robustness, efficiency, a low
failure rate and easy
maintenance. We utilise
Montabert drills in our solutions
as the Montabert drifters are
more reliable and have a higher
brand respect and recognition
compared to local brands.” Siton’s key
models include its two boom coal mining
jumbo, and its one and two boom DW2-50 mining
jumbos which are fitted with the Montabert HC50
as standard or HC109 as an option. The production
drills XTDL-2, XTDL-3 and XTDL-4 all have a
Montabert HC109 drill.
Sandvik operates in China via a JV with Chinese
OEM Lingong known as Lingong Mining Machinery
and Rock Technology Co Ltd (LGMRT) to
manufacture mid-tier level mining jumbos like the
UD392 Underground Drill, while Sandvik Mining
also sells its premium jumbos and production
drills to the biggest mining operators direct.
LGMRT also makes LHDs, underground trucks and
other products in cooperation with Sandvik. It
states: “LGMRT is a joint venture co-established
by Sandvik Group of Sweden and Lingong Group
in May 2016. LGMRT makes full use of Sandvik's
advantages in mining and rock equipment
products and technology, as well as the
advantages of Lingong Group in the mid-end
technology and mid-market operations. It provides
over ten types of mining and rock equipment
Epiroc's rock drill offer to Chinese drill rig OEMs
includes the 18 kW RD 18U for 35-64 mm
holes; a less complex option with
fewer parts and settings
which is intuitive to
maintain and
overhaul
products in four categories for the Chinese
market, other BRIC countries, and countries along
the Belt and Road, eg surface drill rigs,
underground loading and hauling equipment,
underground trucks and underground drills.”
Epiroc is an important player in China both with
its main global range of jumbos and production
drills but also through sales of its rock drills
independently to Chinese drill OEMs. These are in
the main RD drifters dedicated to the Chinese
market rather than the COP drills. These include
the RD 22U, a straightforward hydraulic rock drill
for underground production drilling applications
(64-102 mm) as well as the 14 kW RD 14U and 18
kW RD 18U both for 35-64 mm holes. All these
drills are less complex with fewer parts and
settings so are intuitive to maintain and overhaul.
Discussing Chinese drifter companies, the
largest is Zhangjiagang Free Trade Zone Yongda
Machinery, a Taiwan company, with a factory in
Jiangsu on mainland China, which has seen
continual growth in recent years. Its models
include the Yonda brand hydraulic drifters YHD90
(13 kW) and YHD210 (13 kW) as well as the
YHD950 (25 kW) and YYG265 (35 kW). Aside from
Yongda and its Yonda products there is
Lianhuashan Rock Tools (LHS) in Huludao City,
Liaoning Province with its main models of drifter
being the HYD200 and HYD300. This is a
traditional local company which benefitted from
technology transfer from Secoma in the early
1980s, when Secoma sold the technology of its
Hydrastar 200 and its two boom jumbo to China.
Lianhuashan states: “In 1986, LHS imported
production technology for the HYD200 hydraulic
drifter from Secoma France and manufactured the
first Chinese hydraulic drifter. Continuously
strengthening innovation, research and
development, LHS successively launched the new
products HYD350E and YD150, and upgraded
products of the HYD200E and HYD300E on the
basis of HYD200 and HYD300. The introduction of
the new products expands the product line of
hydraulic drifters, and meets customers'
requirements on hydraulic drifters for different
functions.” As an example, compared to the
HYD200, LHS says the HYD300E has the
advantages of optimised rotation structure, leak
reduction, significantly improved stability, high
adaptability for complicated conditions and low
maintenance cost.
