建井期间竖井多中段提升施工方案研究

Study on the Construction Scheme of Multi-middle Shaft Lifting During Construction

在整个矿山建设工程中,竖井施工结束后,由竖转平施工中段及溜破系统等工程成为制约建井工期的关键因素。由于各个矿山的特点和要求不同,对于无法立即进行井筒永久装备的工程来说,此时利用凿井期间的施工装备来施工中段工程就成了建设及施工单位的共同选择。对于非煤矿山而言,大量无轨设备的使用使得罐笼+有轨矿车运输提升成为了过去式,同时,多中段同时施工也给矿井提升系统带来各种问题,如何保证多中段同时施工的提示系统安全运转,也就成为了一个新的课题。

In the whole mine construction project,after the completion of the shaft construction,from the vertical to the horizontal construction of the middle section and slip system and other projects become the key factors restricting the construction period of the well.Due to the different characteristics and requirements of each mine,it is a common choice for the construction and construction units to use the construction equipment during the sinking period to carry out the mid-course construction project for the projects that cannot be carried out immediately with permanent wellbore equipment.For non-coal mines,the use of a large number of trackless equipment makes the hoisting of cage+railcar transport become the past.At the same time,the simultaneous construction of multiple middle sections also brings various problems to the mine hoisting system.How to ensure the safe operation of the prompt system for the simultaneous construction of multiple middle sections has become a new topic.
