| 摘 要： | 确定合理的封孔深度就是要最大限度抽出煤体中赋存的瓦斯,同时有利于瓦斯的抽采和煤体卸压。通过钻屑法确定合理封孔深度,既能保证最大限度抽出煤体中赋存的瓦斯,又有利于煤层内瓦斯抽放管路的不致于煤体卸压而压裂。

| Abstract: | Determining the reasonable hole sealing depth is helpful for the gas suction and pressure release in seam body.The paper introduces the method of drilling bits to determine the reasonable hole sealing depth,which not only guarantees the utmost gas suction from seam body,but only avoid the fracturing of gas suction line. |
