摘要
经坊矿3-边角06工作面,由于矿井采区布置与地质条件限制,形成了边角煤工作面。运用理论分析的方法对工作面液压支架工作阻力以及工作面的循环采出量进行了计算;结合边角煤工作面的实际条件与设备条件对边角煤工作面的采煤工艺进行了设计,保障了矿井的安全高效作业,为条件相似矿井的边角煤工作面开采提供了实践指导与理论支撑。
In Jingfang Coal Mine,due to the limitation of mining area layout and geological conditions,a boundary coal working face has been formed.Using theoretical analysis method,the working resistance of hydraulic support in working face and the production capacity of working face were calculated.Combining with the actual conditions and equipment conditions of boundary coal face,the mining technology of boundary coal face was designed.The research guarantees the safe and efficient production of the mine,and provides practical guidance and theoretical support for the mining of boundary coal face in similar conditions.
