摘要
阐述了水力疏松工艺系统及设备选型,研究了水力疏松的注水参数,并对防突效果进行了考察。试验表明在严重突出矿井采用水力疏松措施,可有效地消除激发突出的应力、大幅度地释放煤体中的瓦斯、增大煤体抑制突出的阻力、很好地起到了综合防突及降尘作用。
The paper introduces the application of the hydraulic loosening including its technical system, equipment model selection, water injection parameters and the effects on outburst prevention in Aiheshan Colliery, which shows that the hydraulic loosening measures can eliminate the stress stimulating outburst, release the gas in coal, increase the resistance suppressing outburst and play a comprehensive role in outburst prevention and dust removal.
