摘要: 煤矿瓦斯抽采钻孔的封孔方式有好几种,相关实验数据显示,并不是所有的封孔材料都能够对钻孔煤岩层裂
隙起到封堵效果。再者钻孔的裂隙范围较为模糊,封堵的深度不够,在注浆过程中没有注意对压力进行调试等,都会对
煤矿瓦斯抽采封孔效果造成一定的影响。基于此,从煤矿瓦斯抽采钻孔的角度出发,对抽采钻孔的主要封孔方式进行详
细的说明。

Abstract: There are several sealing methods to seal the gas drainage boreholes in coal mines. The relevant experimental data
show that not all sealing materials can block the cracks in the coal seam. Moreover, the fracture range of the borehole is relatively
vague, the sealing depth is not enough, and the pressure is not adjusted during the grouting process, which will have a certain
impact on the sealing effect of gas drainage in coal mines. Based on this, from the point of view of coal mine gas drainage
boreholes, this paper gave a detailed description of the main sealing methods of the drainage boreholes.

Key words: gas of coal mine; drainage boreholes; sealing methods
