鹤壁六矿继储煤2000多吨的中煤仓于1989年2月交付使用和正在掘砌的东大巷进尺300余米后,又一改扩建重点项目—主井筒延深工程于1990年1月2日揭开战斗序幕拉响了第一炮。 1990年是鹤壁六矿改扩建成生产能力120万吨矿井的关键性一年,而延深113米、直径5米的主井筒工程,是一项十分紧迫和艰巨的任务,也是今后拆除主井筒现有的绞车、井架和井筒内的全部提升装置,重建一个高度54.2米的井搭,在井塔上安装多绳摩擦绞车,改6吨箕斗为12吨箕斗扩大提升能力,彻底改变该矿的生产面貌的前期工程。 为保持主井延深期间不影响煤炭正常生产,节约投资,缩短工期,保证施工质量,安全,该矿利
After more than 2000 tons of coal mines were delivered and used in February 1989 by Hebi No. 6 coal mines more than 300 meters after they were dug up, the key project of the expansion project was renewed. The main wellbore extension project was completed in 1990 Opened on the 2nd of the battle kicked off the first shot. 1990 is a crucial year for Hebi No.6 Mine to be rebuilt into a 1.2 million mt mine. However, the main borehole project with a depth of 113 meters and a diameter of 5 meters is a very urgent and arduous task. It is also the task of demolishing the main borehole Existing winches, derricks and all hoisting devices within the wellbore rebuild a well of 54.2 meters in height, install a multi-rope friction winch on the well tower, and change the 6-ton bucket to a 12-ton skip to expand the lifting capacity and completely change the Mine production outlook of the early works. In order to maintain the main shaft does not affect the deepening of the normal production of coal, saving investment, shorten the construction period, to ensure the construction quality and safety of the mine
