西部矿区深立井临时改绞方案优化

Optimization of Deep Shaft Temporary Reconstructions in Western Mining Area

针对西部矿区深立井临时改绞问题,以新疆塔什店一号矿井主副井与风井采用对角式布置条件为例,分析了影响临时改绞的主要因素,采用多方案综合对比的方法,对深立井临时改绞方案进行了优化。结果表明:井筒直径、提升能力、提升装备和提升时间是影响立井临时改绞的主要因素;选择主井和风井进行临时改绞,副井直接进行永久装备可满足平巷掘进工程提升能力的需要;主井临时改绞宜采用1对1.5 t矿车双层单车临时罐笼的方式;风井临时改绞可借鉴金属矿山的成功经验,宜采用装备1个3 m3箕斗和1个1 t双层罐笼采用双钩混合提升方式。研究成果对加快塔什店一号矿井建设速度,缩短矿井建设工期具有指导作用,同时为新疆等西部矿区深立井临时改绞方式的选取提供了经验参考。

In view of the issue on the temporary reconstruction of deep vertical shaft in the western mining area, and taking the diagonal arrangement of the main shaft,auxiliary shaft and ventilation shaft in Tashidian NO. 1 coal mine, Sinkiang for example,the main factors influencing the temporary reconstruction were analyzed,and the temporary reconstruction of deep vertical shaft was optimized with comprehensive comparison of alternative methods. Results indicated that diameter of shaft, hoisting capacity, hoisting equipment and lifting time are the main factors influencing temporary reconstruction; Selecting main shaft and ventilation shaft for temporary reconstruction and permanent equipment for auxiliary shaft can meet the needs of the hoisting capability for roadway driving engineering; Temporary reconstruction of main shaft appropriately adopts a pair of 1.5 t mine car with double-deck single car as temporary cage ;Temporary reconstruction of ventilation shaft can draw lessons from the successful experience of metal mine, and adopts the double-hook mix hoisting way equipped with a 3 m3 skip and a 1 t double-deck cage. The research has a guiding role in accelerating construction speed and reducing the constructing period for Tashidian NO. 1 coal mine. At the same time,it provides the reference for temporary reconstruction of deep vertical shaft in Sinkiang and other western mining areas.
