Lam Tei Quarry

Hugh Farmer:

“Today, under a plan formulated in 1989, the three remaining operational quarries in Hong Kong are being rehabilitated to form green areas for future development. Shek O (completion in 2009), Anderson Road (2013) and Lam Tei (2015) quarries are being rehabilitated under contracts that involve major recontouring to soften the appearance of the angular quarry profile, tree and shrub planting, and erosion control. A similiar rehabilitation contract was completed in 2002 at Lamma Quarry to form a green site of  0.49 square kms. (Sewell 2009)

Members of The Institute of Materials, Minerals and Mining, HK Branch made a Technical visit to Lam Tei Quarry on 8th Dec 2012. Here is a report:  http://www.iom3.org.hk/event/technicalvisittolamteiquarry8december2012

report 2011 http://www.epd.gov.hk/epd/SEA/eng/files/Quarry%20Study%20Brief%20(Part%20Version%20covering%20SEA).pdfLam Tei Quarry will be the only existing quarry left in Hong Kong after 2015, with rock reserves sufficient for another quarrying contract until 2022. Development of a new local quarry site is of strategic importance to Hong Kong’s construction industry in regulating crushed rock products supply. It would also enhance our capacity to recycle surplus rock generated from local construction projects for beneficial use. While it is planned that the operation of Lam Tei Quarry will continue until 2022, there is a need for the CEDD to conduct studies on development of new quarry sites to meet long-term needs.

http://hkss.cedd.gov.hk/hkss/eng/education/GS/eng/hkg/chapter8.htmRehabilitation contracts involve the landscaping of the quarries, and the production of saleable rock products. Thus, Anderson Road Quarry (Figure 23) will produce 50 million tonnes of rock up to 2013 (2.6 million tonnes in 2006), Shek O Quarry will produce 23 million tonnes, and Lam Tei Quarry will produce 6.5 million tonnes.

Widely recognised as one of Hong Kong’s leading aggregate producers and distributors, Anderson Asia operates a granite quarry at Lam Tei, near Tuen Mun in the New Territories.

At Lam Tei Quarry, operated by Asia Stone, a modern Cedarapid/EIJay crushing and screening plant continues to set new standards for the industry in Hong Kong. Stage I of the plant, which became operational in 1983, is capable of producing 600 MT per hour of 75mm, 40mm, 20mm and 10mm aggregate and 5mm crushed rock fines. Stage II will provide additional capacity to meet future needs, and when in operation the plant will have a total capacity of over 1,000 MT per hour.

Lam Tei Quarry is located about 3 km north of Tuen Mun New Town, covering an
area of about 30 hectares. The contract (No. 444/81) was signed in January 1982 and was
completed in June 2007. The total amount of excavated rock derived from the quarry under
the contract was about 27.1 million tonnes. The following works were carried out under the
contract:
(a) formation of a new landform consisting of 9 benches, separated by 15 m high 60° to
70° cut slopes, and a platform of 14.5 hectares;
(b) re-vegetation of the final landform to a stable condition to eventually blend in with
the surrounding natural environment;
(c) provision of a self-sustaining ecosystem with a similar bio-diversity to the
surrounding environment; and
(d) provision of a natural and safe environment for future land use of the site.
Quarrying in Lam Tei continues with a new rehabilitation contract (No. GE/2006/03)
following the completion of the previous contract. The contract was signed in October 2006
for completion in July 2015. The estimated total amount of excavated rock derived from the
quarry under the new contract is 6.5 million tonnes. The quarry supplied 0.86 million tonnes
of rock products to the local construction industry in 2010. The works under the current
contract are essentially the same as those of the completed contract in 2007, except that the
final platform will be lowered by a further 20 m and two new benches separated by a
maximum of 10 m high 60° to 70° cut slopes will be formed.
The vegetation planted under the completed contract has been well established on
the benches and the planting works under the current contract are in progress.
