摘要
分析了高压磨料射流割缝防突机理,在国内率先研制出用于高突掘进工作面的高压磨料割缝设备,并在平煤公司十二矿17180掘进工作面进行了工业性试验应用。试验期间,瓦斯释放空间大幅增加、掘进速度显著提高、煤层瓦斯压力得到了有效的释放,且该设备割缝效果好,操作方便,使用安全,不受巷道条件限制,适用性好。
With the analysis on the outburst mechanism of the high pressure abrasive hydraulic jet cutting,a high pressure abrasive hydraulic jet cutting equipment for the mine heading face with high outburst was first developed in China.The hydraulic pressure jet cutting equipment had an industrial trial in No.17180 heading face of No.12 Mine,Pindingshan Coal Mining Group Corporation.During the trial period,the gas emission space had been highly increased,the heading speed had been obviously improved and the gas pres...
