综采工作面煤层脉动高压注水技术研究

Research on coal seam pulse high pressure water injection technology in fully mechanized working face

为了煤矿综采工作面粉尘率得到有效降低,采用脉动高压注水与静压注水技术相结合的方法对煤层进行注水,使得煤层具有较好的增水率;同时,呼吸性粉尘浓度、非呼吸性粉尘浓度和总粉尘浓度均得到了较大幅度降低,为改善工作人员工作环境和煤矿企业安全高效生产奠定了良好基础。

in order to effectively reduced the dust rate fully mechanized face, using the method combined with pulse high pressure water injection and static pressure water injection technology, which improve the seam moisture content, at the same time, concentration of respiratory dust, non respirable dust and total dust concentration were greatly reduced, laid a good foundation for improving the working environment and staff of coal mine safety and efifcient production.
