1) outburst fracturing
爆发致裂
2) blast cracking
爆破致裂
1.
To improve the gas drainage rate from coking coal seam with high gasification,lower permeability and difficult drainage,the paper had a study on hydraulic pressure cracking and blast cracking technologies,which could make certain cracking along the borehole.
为提高煤化程度高、低透气性难抽放的焦煤瓦斯抽放率,论文研究应用水压致裂和爆破致裂技术,可产生适当数目的孔边裂纹和贯通裂纹,实验发现钻孔周围的裂纹数目、几何形态、连通状况等与致裂压力、煤岩体力学性质、应力分布、钻孔直径和周围介质中膨胀波传播速度相关,借助钻孔水压致裂和爆破致裂技术可以提高煤层透气性。
2.
Based on the low borehole gas drainage rate in high gas seam with low permeability,deep-hole cumulative blast cracking technology in coal bed was presented to improve the permeability.
针对高瓦斯低透气性煤层钻孔瓦斯抽放效率低的问题,以郑州煤炭工业(集团)有限责任公司大平煤矿为例,提出了煤层深孔聚能爆破致裂增透方法。
