摘要
充分考虑煤矿瓦斯赋存条件的特点,研究适宜的瓦斯抽采钻孔封堵材料及其配套工艺是我国煤矿安全技术人员竞相追逐的热点之一。简要分析了煤矿井下巷道内空气进入瓦斯抽采钻孔的路径,归纳了瓦斯抽采钻孔封堵材料及其配套工艺作业效果的影响因素,并重点阐述了目前我国煤炭行业常用的封堵材料及其配套工艺的研究进展,进一步提出了存在的问题及未来的研究方向。
It was one of the hot spots that coal mine safety technicians were competing for studying the suitable sealing material and its matching technology for gas drainage and drilling with the characteristics of coal mine gas occurrence conditions fully considered. We briefly analyzed the path of air entering the gas extraction borehole in the roadway of underground coal mine,summarized the influencing factors of sealing materials and supporting technology for gas extraction drilling, emphasized the research progress of plugging materials commonly used in China’s coal industry and their supporting technologies, and put forward the existing problems and future research directions.
