Dowdens Pumping & Water Treatment's Mackay branch was engaged by Anglo American - Moranbah North Coal Mine to design, engineer and build a boost pump station to supply raw water to the longwall area. Dowdens Pumping & Water Treatment designed and built the longwall boost pump station utilising dual variable speed pumps to enable the station to cater for varying duties as the underground workings progress further away from the station.
Anglo American's Moranbah North coal mine began operation in 1998 as an underground longwall mine and currently supplies 4.5m tonne annually of high fluidity premium hard coking coal mainly for export to iron and steel manufacturers in Japan, Korea and Taiwan.
All design, fabrication, installation & commissioning of the longwall boost pump station was undertaken by Dowdens Mackay's in-house Engineering, Fabrication & Workshop Departments and all electrical componentry of the longwall boost pump station was supplied, installed and commissioned by Major Electrical. With a history of successful installations over the past 20 years throughout the Queensland Mining Sector Dowdens Pumping & Water Treatment have the ability to expertly design / manufacture / install and commission specialised pumping and water treatment solutions that are built primarily in-house & onsite to our client's specific unique requirements.
Dowdens dedicated departments of industry trained engineers, draftsmen, project managers, sales staff and tradespeople including fitters, mechanics, polywelders, machinists, plumbers, electricians and boiler makers enable us to offer an unmatched range of world-class engineering solutions for any type of water management project. We truly are Queensland's premier one-stop-shop for pumping and water treatment systems!
"The longwall booster pump station was taken underground into immediate service after only a couple of days. There is normally a one or two month delay with above ground commissioning for all new units. Since the pump powered up after the first run it has not stopped running and is sitting at only 10% duty. The longwall has cut 128,000 tonnes so far which is exceptional. Any future boost pump orders from Dowdens Pumping & Water Treatment will not require any changes to the design or manufacture saving us both time & money."
The pump station boosts water pressure to the longwall currently some 6,000m away. Comprehensive 'pre-challenge' testing was completed prior to the station being transported to site, with all parameters being set during this time. Dowdens internal teams of specialised engineers, CAD draftsmen and tradespeople were able to design and build the station on time and to a tight budget, with Anglo American extremely happy with the work undertaken and product supplied.
