摘要
以高压水射流技术的理论为基础,对现有的高压水射流装置中的关键设备——射流器和喷嘴进行了技术革新,首次设计出适合煤矿井下使用、用于防突预抽切割煤体的高压水射流装置。现场试验表明,不仅操作简单方便,而目切割效率很高,效果很好。
Base on theory of high-pressure water jet technology, the crux mechanism, jet and nozzle in existing high-pressure water jet device have been innovated, a new high-pressure water jet device suitable for shaft and bleed-proof forepumping cutting coal body has been put forward, the field trial in BaiJiao coal mine shows that it is simple and convenient to operate, cutting efficiency is high.
