   Bucyrus-Equipped Newlands Longwall Sets New Record
February 16, 2010


    斯特拉塔集团所属的位于澳大利亚昆士兰州波文盆地的纽兰诺尔森长壁矿井创下了2009年新的澳大利亚年产量记录。
    该矿井采用比塞洛斯EL3000采煤机创下了2009年澳大利亚8,318,421吨的年产量记录,较此前该集团贝尔塔纳矿2007年的7,627,644吨的记录增长了9.1%。
2009年5月,纽兰诺尔森矿还创下了澳大利亚961,891吨的月产量记录,而2009年10月,该矿进一步将磁记录又提高到了1016,794吨。尽管在年中换面生产,但是该矿还是创下了年生产记录。
    自从2006年装备了新的比塞洛斯EL3000采煤机后,四年来纽兰诺尔森矿的生产能力稳步提高。2009年830万吨的产量差不多将第一年的产量449万吨增加了一倍。
纽兰诺尔森长壁矿井完全装备的是比塞洛斯产品,大部分产品是早在1998年交付的,但是仍运行良好。装备EL3000采煤机的长壁工作面总的装机功率1590kW,其中的切割滚筒功率为2×650kW。采煤机为全自动形式,牵引功率2×125kW。工作面配备的是181架双缸液压支架,其疲劳载荷913吨,工作高度3-5米,由比塞洛斯PM4电液控制系统控制。
    312米长的工作面输送机为比塞洛斯PF5/1342,链条48mm×144/166,驱动系统采用3×855kWCST驱动装置。另外375kW的PF4/1532桥式转载机和400kW的SK11/18破碎机也是由比塞洛斯公司提供的。
    纽兰诺尔森矿生产的是出口动力煤,其井工和露天开采条件都很具有挑战性,该矿井位于沿海中心城市迈凯以西130公里,距离铁路运煤枢纽Abbot Point171公里。
    Xstrata’s Newlands Northern underground mine – in the Bowen basin, Queensland, Australia – set a new Australian annual production record in 2009.
    Using a Bucyrus EL3000 shearer, Xstrata’s Newlands Northern underground mine – in the Bowen basin, Queensland, Australia, set a new Australian annual production record in 2009. At 8,318,421 tonnes (9,159,490 US tons), the record is an increase of 9.1% on the previous high of 7,627,644 tonnes (8,408,038 US tons) set in 2007 by fellow Xstrata mine Beltana in NSW also operating with a Bucyrus EL3000 shearer.

    In May 2009, Newlands Northern Mine also set a new Australian monthly productivity record of 961,891 tonnes. The mine further improved on this by extracting 1,016,794 tonnes in October 2009. The annual production record was achieved despite a longwall move mid year.

    Productivity at the Newlands Northern Mine has been steadily increasing in the four years since a new Bucyrus EL3000 shearer was installed in 2006: The 8.3 million tonnes extracted in 2009 is getting close to double the 4.49 million tonnes mined in the first year of operation.

    The Newlands Northern Mine longwall is completely Bucyrus-equipped, with most of the equipment originally being supplied to Newlands Southern Mine as early as 1998 but still performing well. The longwall works with an EL3000 shearer with total installed power of 1.590 kW including cutting power of 2 x 650 kW. The shearer is fully automation-capable and works with haulage power of 2 x 125 kW. The longwall is further equipped with 181 two-leg roof supports with a yield load of 913 tonnes and a working range of 3 - 5 meters, automated with Bucyrus’s PM 4 electrohydraulic control system.

   The face conveyor for the 312 m longwall is a Bucyrus PF 5/1342 with a 48 mm x 144/160 combichain and 3 x 855 kW CST drives. The 375 kW PF4/1532 beam stage loader and 400 kW SK11/18 coal crusher are also supplied by Bucyrus.

    The Newlands mine produces export thermal coal from underground and open-cut operations in an extremely competitive environment. It is located 130 km west of the coastal centre of Mackay and 171 km by rail from the Abbot Point coal terminal.
