铜矿峪矿二期工程是铜矿峪矿生产衔接的重要工程,计划在2009年投入生产,预计投产后每年的出矿能力为600万 t,力争达到800万 t,是目前国内最大的非煤地下矿山。为加快施工进度,现在铜矿峪矿每年的掘进任务在14万 m~3以上,要排放毛石40多万 t,这些废石都要通过混合井提升到690水平,再转运到箕斗井,由箕斗提升至930地表排放。混合井箕斗提升存在着矿石和粉矿的洒落问题,尽管在设汁上采取了相应的技术措施,在生产上加强管理,但不能彻底解决粉矿的洒落问题。进入深部施
The second phase project of Tongkuangyu Mine is an important project that connects the production of copper mine and the Yuyu Mine. It is planned to put into production in 2009 and is expected to have an annual output capacity of 6 million tons and strive to reach 8 million tons after it is put into production, which is currently the largest non- Underground coal mine. In order to speed up the construction progress, the annual mining task of Tongkuangyu Mine is 140,000 m 3 or more, and more than 400,000 tons of rock are discharged. These rock waste must be raised to 690 level through the mixing well and transferred to the well , Raised to 930 by the skip surface discharge. There is the problem of spilling of ores and silt in the mixing well, while sprinkling of ore ores can not be completely solved although the corresponding technical measures have been adopted in the design of juice and the management of production has been strengthened. Into the deep facilities
