3312工作面过断层采煤工艺研究

Study on Mining Technology of Cross Fault in the 3312 Working Face

郭庄煤业3312工作面存在多处地质断层,对采煤安全和采煤效率有很大影响。选取3312工作面TF-1断层为研究对象开展过断层采煤工艺研究,根据TF-1断层参数制定了以挑顶卧底法为主,调整割煤高度法为辅,并配合震动炮截割的过断层采煤工艺方案,为煤矿过断层采煤工艺的选择提供了新的参考。

There are many geological faults in the 3312 face of Guozhuang Coal Industry,which have great influence on coal mining safety and coal mining efficiency.Selecting 3312 working face TF-1 fault as the research object to carry out the cross fault mining technology research,according to the TF-1 fault parameters,the coal mining technology scheme through fault is formulated,which is mainly based on the top lifting and undercover method,supplemented by the method of adjusting the cutting height,and combined with the vibration gun cutting.It provides a new reference for the selection of coal mining technology through fault.
