综放工作面对接技术研究与实践

Practices and Research Comprehensive Mining Face Connection

矿井地质构造复杂,根据工作面实际断层情况,避开断层对工作面影响范围,对综放工作面进行分块段开采,在回采过程中面临着支架、运输机中间对接和延长等技术难题。里段工作面回采期间,控制回采设备相对工作面的位移变化,最终实现了外段工作面对接点的精准控制,确保了工作面成功对接。总结出了成熟经验,为今后类似条件下回采提供参考和借鉴。

As the geology structure of mining is complex,according to the fault of working face.Avoid range of the influence of faults on theworking face ,use block mining on Comprehensive Mining Face.In Stoping process,Technical problems such as bracket and transportconnection frequently occured. In Inner face Stoping process ,Control the Displacement change of mining equipment.Finally,Accurate controlon outer face is achieved, and ensure Comprehensive Mining Face is connectied.This text sum up some experience,and it can providereference for stoping process when in Similar situations.
