摘要
根据东曲矿工作面煤层状况,通过合理选择煤层注水钻孔施工工艺,优化煤层注水参数,减少影响煤层注水效果的因素,加强煤层注水的日常管理,使采煤工作面各回采工序产尘量大幅度降低,收到了良好的效果,从技术源头上杜绝了煤尘的产生。
According to the coal seam condition of working face in Dongqu coal mine, through the reasonable choice construction technique of coal seam injection drill hole, optimizes coal seam injection parameter, reduces the factor of influencing coal seam injection effect, strengthens current management of coal seam injection, causes the quantity of dust to reduce vast scale in various mining procedure of the coal mining face, receives the good effect,stops the coal dust production from the technical source.
