摘要
应用数值模拟方法验证了高压水射流切割技术能够克服地质条件等诸多因素的限制,实现本层煤的卸压,卸压范围可达到5m以上,卸压效果较好。
This paper applied numerical simulation to researching pressure-relief effect. Result showed that high-pressure water jet technology could overcome many restrictions such as geological conditions. Result also showed that pressure-relief range of current coal seam was over 5m and this indicated pressure-relief effect was good.
