复采煤综采工作面开采技术探讨

Complex Coal Fully Mechanized Mining Face Technology

康城煤矿为资源枯竭型矿井,为延长矿井寿命,充分回收煤炭资源,在原-100m水平126采空区范围内,合理布置成复采工作面,针对原采空区顶板胶结性差、复采巷道施工及复采面开采的特点,在复采工作面应用了综合开采技术并取得了显著效果。

According to poor cementation of the former coal mine gob roof in kangcheng mine, second mining roadway construction and second mining face situation, complex integrated mining technology was conducted. Practice has proved that： optimizing the use of appropriate methods and roadway mining technology to ensure safe mining face as much as possible while the recovery coal resources, provided reference and guidance for similar mine.
