摘要
瓦斯抽采是治理煤矿瓦斯最有效的措施之一,但常用的钻孔密封技术存在封孔效果差,封孔设备复杂、昂贵等诸多缺点,直接制约了矿井瓦斯抽采工作。通过分析目前常用的封孔技术,研究该技术对瓦斯抽采浓度的影响因素,给出了一种新型的胶囊贴封孔器,对提高煤矿瓦斯抽采能力具有重要意义。
Gas extraction is one of the most effective measures to control gas in coal mine. But the common borehole sealing technology has many disadvantages,such as poor sealing effect,complicated and expensive sealing equipment,which directly restrict the mine gas extraction work. By analyzing the influence of the common borehole sealing technology on the gas extraction concentration,a new kind of capsule borehole packer is proposed,which is of great significance to improve the gas extraction capacity of coal mine.
