梅花井煤矿巷道穿层掘进施工工艺研究

Study on Construction Technology of Roadway Tunneling through Layersin Meihuajing Coal Mine

以梅花井煤矿111808工作面运输巷回风联络巷穿层掘进为例,研究了穿层掘进中存在的问题,并提出相应的措施,通过实际应用,快速形成了连续运输系统,确保巷道安全高效掘进,保障了矿井正常采掘接续。

The cross-layer tunneling of transport roadway and return airway crossheading for the 111808#working face of Meihuajing Coal Mine was taken as an example to study the problems existing in the tunneling through layers and put forward corresponding measures.According to the effect of practical application,a continuous transportation system is quickly developed,which ensures safe and efficient transportation of roadway,and facilitates the normal mining-excavation succession in the mine.
