The safe and efficient mining of outburst-prone coal seams is an important means to improve economic benefit of an outburst mine.突出危险煤层的安全、高效开采是突出矿井提高经济效益的重要措施。
The study results indicate that the fault distribution in both outburst and non outburst mine fields are all follow the fractal la.研究结果表明,突出与非突出井田的断层分布均服从分形规律;井田中断层分布的分维值与瓦斯突出之间存在着正相关关系等重要结论。
