薄煤层保护层开采瓦斯治理综合措施

Comprehensive Measures for Gas Control in the Protective Layer of Thin Coal Seam

结合实际矿井薄煤层保护层工作面开采情况,从薄煤层保护层开采中保护层瓦斯抽采、保护层回采期间瓦斯治理及保护层开采三方面讨论了薄煤层保护层开采瓦斯治理综合措施,并对其瓦斯治理效果进行了分析。薄煤层保护层开采瓦斯治理综合措施的应用有效控制了本煤层工作面瓦斯大量涌出和上隅角瓦斯超限问题,同时实现了对近距离被保护煤层的瓦斯卸压,确保了矿井生产安全。

Combined with the actual mining situation of the protective layer of thin coal seam in mines, this paper discussed the comprehensive measures for gas control in the protective layer of thin coal seam from the aspects of gas drainage in protective layer during mining the protective layer of thin coal seam, gas control during protective layer mining and the mining of protective layer of thin coal seam. And the effect of gas control was analyzed. The application of comprehensive measures for gas control in the protective layer of thin coal seam effectively controlled the gas outburst in the coal seam face and the over-limitation of gas in the upper corner, and at the same time realized the gas pressure relief of the near protected coal seam to ensure the safety of mine production.
