| 摘 要： | 针对目前国内顺层瓦斯抽采钻孔封孔质量差,钻孔有效抽采期偏短的技术难题,提出了带压注浆封孔技术。阐述了带压注浆技术的基本原理,并对其配套材料的性能和设备进行了研究。该封孔技术在宣东二号煤矿开展了现场工业性试验。结果表明:带压注浆封孔技术能增加封孔深度,实现了封孔工艺由手工向机械的转换,提高了抽采钻孔的封孔质量,使瓦斯抽采平均浓度提高了40%左右,单孔平均多抽瓦斯量约1 036.8 m3。

| Abstract: | The sealing quality of domestic gas extraction drilling is poor at present,and the effective gas drainage period of holes is short,so grouting sealing under pressure technology is proposed as a solution to this problem.The basic principles are described and the performance of supporting material and equipment were studied.An industrial scale test of this technology was carried out at the Xuandong II mine.The results show: Grouting sealing under pressure technology can increase the depth of the sealing proce... |
