摘要
文章分析了在复杂地质条件下测定瓦斯含量时下行岩孔取煤样的技术难点,提出对钻孔注浆封堵含水裂隙后再取煤样的方法来测定瓦斯含量,为复杂地质条件下岩孔取煤样提供了一个新的方法。
The paper analyzes the complicated geological conditions in the determination of Downward the rock hole when the gas content of coal samples taken technical difficulties made for drilling grouting sealing cracks and then take the coal moisture content of the method to determine gas content,for the rock under complicated geological conditions take coal hole offers a new approach.
