矿用封孔泵是聚氨酯类封孔剂的配套设备，它是利用手动操作进行注浆作业的一种新型装置，主要适用于瓦斯抽放钻孔的密封，特别适合于煤矿井下风、电、乳化液等动力源难以解决的地方，可大幅度改善瓦斯抽放钻孔的密封效果，提高瓦斯抽放浓度。设备的动力完全来自人力，避免了矿井下电气等不安全因素的影响。 该设备使用方便，封孔效率高，安全可靠。
Mine sealing pump is a kind of matching equipment of polyurethane sealing agent. It is a new type of device which uses manual operation to carry out grouting operation. It is mainly suitable for sealing gas drainage holes, especially for places where the power sources such as wind, electricity and emulsion are difficult to solve, which can greatly improve the sealing effect of gas drainage holes and improve the gas drainage concentration. The power of the equipment completely comes from manpower, which avoids the influence of unsafe factors such as electrical under the mine. The equipment is easy to use, high efficiency of hole sealing, safe and reliable.
