摘要
介绍了利用风煤钻施工钻孔,在采场动压作用下煤体产生裂隙释放瓦斯,然后利用抽排设施抽放瓦斯,治理采面局部高瓦斯区域的方法。
The method of drilling by the wind coal drill, the coal body produces the crack and releases gas under the conditions of the dynamic pressure function of mining field, then draining gas with drainage facility to govern the local high gas region at working surface are introduced.
