摘要
为了降低立井揭煤过程中发生煤与瓦斯突出的危险性,指导立井防突工作开展,采用理论分析与工程实践的方法,以某矿立井揭82煤为例,对立井揭煤防突技术的具体流程、钻孔布置以及效果考察等进行了系统的论述。得出结论:钻孔预抽是立井防突工作的重中之重,只有钻孔有效、系统合理,才能从根本上遏制立井突出事故。
For the purpose of reducing the coal and gas outburst danger of uncovering coal in shaft and guide the outburst prevention work in mine shaft,taking uncovering No. 82 coal seam in vertical shaft of one coal mine as an example,a systematic description of the construction procedure,borehole layout method and effect measuring method was given during the outburst prevention work in uncove- ring coal. It gets conclusions that, advanced gas drainage by using boreholes is very important in outburst prevention work of vertical shaft,only effective boreholes and reasonable system can help reducing the outburst risk fundamentally.
