前混和磨料水射流切割安全放顶研究

Study on Safety Collasp Roof with Pre-mixed Abrasive Water Jet Cutting

通过对前混合式磨料水射流切割的切割能力及在不同瓦斯条件下的切割安全性进行分析,认为利用前混合式磨料水射流切割技术可以解决目前坚硬及锚杆、锚索等支护顶板放顶难的问题。设计并建立了前混合式磨料水射流切割实验系统及实验方案,分析了切割能力的影响因素。

The cutting ability and the safety in different conditions of gas of the premixed abrasive water jet cutting are analysed. The problem that the current rigid and bolt, cable supporting roof collasp difficult use of pre- mixed abrasive water jet Cutting technology can be, solved. The pre - mixed abrasive water jet cutting systems and experimental pilot program are designed and built. The influencing factors of the cutting ability are analysed.
