摘要:
为分析基于液电效应的高压电脉冲致裂煤体效果,采用电脉冲应力波实验和微观观测方法对潞安矿区煤样裂隙发展过程及其特征进行研究。结果表明:液电效应能明显致裂煤体,且作用次数越多,煤体裂隙密度越大、裂隙网络越贯通,同时煤体孔裂隙等结构薄弱部位的存在能促进裂隙的发育;液电效应对煤体作用可分为4个阶段,其中裂隙快速发展阶段是适合现场作用阶段;高压电脉冲通过液电效应产生冲击波和其他次生作用,且对煤体组成成分无影响;在现场应用中,应充分考虑煤体性质、钻孔布局等,采用“单点多次、多次连续、分段进行、全孔作业”的作业方式。该实验研究为基于液电效应的高压电脉冲技术应用提供支撑。
Abstract:
In order to analyze the effect of coal crushing by using the highvoltage electrical pulse based on the electrohydraulic effect,the crack development process and its characteristics of coal samples from Lu’an mining area were studied by using the electrical pulse stress wave experiment and the microobservation method.The results showed that the electrohydraulic effect could crush the coal mass obviously,the more the action times,the larger the crack density of coal mass,and the more penetrating the crack network.Meanwhile,the existence of structural weakness positions such as the cracks and holes in the coal mass would promote the development of cracks.The action of electrohydraulic effect on the coal mass could be divided into four stages,and among which,the rapid development stage of cracks was the stage fitting the field action.The highvoltage electrical pulse generated the shock wave and other secondary action through the electrohydraulic effect,without influence on the composition of coal mass.In the field application,the properties of coal mass and the layout of boreholes should be fully considered,and the operation mode of "single point many times,many times continuity,subsection conduct,full borehole operation" should be adopted.The experimental research provides support for the application of highvoltage electrical pulse technology based on the electrohydraulic effect.
