摘　　要：依据平顶山煤业集团一矿具体情况 ,研制出水力疏松防突煤层浅孔注水器。试验表明 ,防突效果取决于合适的水力疏松参数 ,提出注水孔深因地质条件不同而不同 ,对具体煤质注水压力存在最佳值而注水量应控制在一定范围内。Based on the first coal mine situation of Pingdingshan mining group company,water power loosening coal seam flooding equipment is developed.Through test,water result depends on water power loosening parameter,water hole depth depends on geological condition,water power of specific coal has optimum number and water volume is controled within limit the scope.

关 键 词：水力疏松 煤层注水器 防突效果 地质条件 煤突出 瓦斯突出
