摘要
2310综采工作面在收尾前,车集煤矿应用虚中心调斜回采技术,并在工作面调斜回采过程中采取控制顶板和设备的相关技术措施,实现工作面机头大幅度不等长调斜回采,解决了工作面大幅度调斜期间液压支架和输送机等设备的控制难题,为不规则工作面调斜回采提供了宝贵经验。
When finishing 2310 fully-mechanized working face in Juji Coal mine,virtual center regulate inclination mining technology was put into the practice,during the coal winning with roll steering on face,according to the relevant technical measures of roof control and equipment,the large-amplitude and length-variable coal winning with roll steering for drive unit on face was achieved,the device control problem of hydraulic support and conveyor was als solved in the process of the large-amplitude roll steering of working face,which can provide valuable experience for the coal winning with roll steering of irregular working face.
