| 摘 要： | 在深部开采条件下,一些高瓦斯矿井出现了煤与瓦斯突出和冲击地压并存的现象。通过对平煤十矿动力现象资料进行初步分析,提出用煤层注水、深孔卸压爆破和水力压裂技术来防治冲击地压和消除突出危险。结果表明:煤层注水不仅达到了防冲和消突的效果,还有效地降低了粉尘;深孔卸压爆破有效地消除了冲击地压的威胁,水力压裂在消除突出危险方面效果明显。 |

| Abstract: | Under the deep mining condition,some high gas mines appeared the phenomenon that coal and gas outburst go together with rock-burst.According to the preliminary analysis on dynamic phenomenon data,some methods are put forward,such as coal seam infusion,long-hole blasting of releasing pressure along with hydraulic fracturing to prevent rock-burst and eliminate the gas outburst danger.The study results showed that the technology of coal seam infusion not only achieved the effects of preventing rock-burst and reducing the risk of gas outburst,but also reduced dust,the long-hole blasting of releasing pressure eliminated the threat of preventing rock-burst efficiently,and the hydraulic fracturing had obvious effects in removing the gas outburst hazard. |
