针对煤矿井下瓦斯抽放钻孔封孔质量差的现状,平煤十二矿大胆尝试,经过技术研究及工业性实施,最终完成了矿用注浆封孔器的研制开发,该项设备结构简单,操作过程简便可以满足不同孔径瓦斯抽放钻孔的封孔需求,具有普遍使用性,值得在全国煤炭系统推广应用。
Aiming at the current situation of poor sealing quality of gas drainage borehole in coal mine, Pingdingshan No.12 Mine is a bold attempt to finish the research and development of mining grouting and plugging device after technical research and industrial implementation. The structure of this device is simple , The operation process is simple and can meet the sealing requirements of gas drainage boreholes with different pore diameters, and has universal applicability, which is worth popularizing and applying in the national coal system.
