高瓦斯突出煤层群首采保护层立体式瓦斯综合治理技术及应用
|
摘要
为了解决云南省恩洪矿区采煤工作面上隅角瓦斯频繁超限、煤层突出威胁严重的问题,在调研分析区内矿井生产现状的基础上,结合类似条件的淮南、松藻矿区的先进瓦斯治理实践,提出"恩洪矿区瓦斯治理技术路线",选择吉克煤矿作为实践矿井,开发出"首采保护层立体式瓦斯综合治理技术"。结果表明:该技术不仅解决了矿井首采M_7煤层工作面上隅角瓦斯超限难题,而且消除了中远距离被保护层M_2,M_9,M_(11),M_(12)煤层的突出危险性,为区内其他矿井的瓦斯治理工作提供了借鉴。
In order to solve the problems of gas frequently overrun of upper corner and coal seam outburst menace seriously of coal mine working face of Enhong coal mine district of Yunnan province,based on investment of production status,with some advanced gas control practice of similar area as Huainan,Songzao mining area,and then 'gas control technical route of Enhong mining distract' was put forward,it taking Jike coal mine as practice object,and spatial gas control technology of first mining protective layer was developed,the results showed that the difficulty problem of gas transfinite of working face upper corner of M_7 coal seam,and then the outburst dangerous of M_2,M_9,M_(11),M_(12) coal seam were also eliminated,and references for similar situation.
