摘要
随着开采时间的推移,开采深度不断的递增,突出煤矿和突出煤层的数量也在不断增加,开采技术难度不断增大,突出事故率也随之不断提高。区域性瓦斯治理技术的应用给煤矿的安全生产提供了重要保障,体现出了区域性瓦斯治理技术的重要性与必要性。从开采保护层、卸压瓦斯抽放、加强预抽煤层瓦斯等方面对毕节市煤矿区域性瓦斯治理的技术进行探究。
With the time goes by, the mining depth and the quantity of outburst mines and outburst coal seams in Bijie coal mines keeps increasing, which lead to the mining technology become more difficult, and the rate of outburst accidents also continue to improve. Application of regional gas control technology has provided an important guarantee for the safety production of coal mines, reflects the importance and necessity of regional gas control technology. Study the regional gas technology of coal mines in Bijie city from the protecting seam exploitation, pressure-relief gas extraction, and strengthening gas extraction.
