摘要
瓦斯抽放钻孔密封性能的好坏,直接影响着瓦斯抽放浓度的高低及瓦斯抽放效果,双动力封孔注浆泵是基于以上需求开发研制的,其特点是轻型,震动小,注浆速度均匀,注浆量大小便于控制,能够注稠浆。该种设备通过在平煤首山矿的应用,取得了良好的使用效果,值得推广和应用。
The sealing property of gas drainage drilling influence gas drainage concentration and effect directly. Mine double-acting grouting pump is on account of the requirements above and its features are light, low-shaking, even grouting rate, easy-controlling; wide grouting boundary. The equipment has been tested in the shou shan mine of PINGDINGSHAN COAL （GROUP） CO. LTD and received wonderful effect.
