小直径深立井改绞后的提升能力,是矿井二期工程能否实现快速施工的关键所在。刘店煤矿主井井筒净直径5.0m,深678.5m,为小直径深立井井筒。该井筒临时改绞中,为满足矿井二期工程提升能力要求,设计采用了非标铝合金临时罐笼,收到了预期效果。
After the small diameter deep vertical shaft to improve the lifting capacity, is the second phase of the mine can achieve rapid construction of the key. The main shaft of Liudian Mine has a net diameter of 5.0m and a depth of 678.5m, which is a small-diameter deep-shaft well. In the temporary changeover of the wellbore, in order to meet the requirements of upgrading the capacity of the second phase of the mine, a non-standard aluminum alloy temporary tank cage was designed and received the expected results.
