实验室煤与瓦斯突出模拟试验回顾及展望

Review and Prospect on Coal and Gas Outburst Simulation Experiment in Laboratory

为借鉴国内外煤与瓦斯突出模拟试验研究成果,查阅大量相关文献,进行分析和总结。以人们对煤与瓦斯突出试验研究的深入程度为主线,将实验室煤与瓦斯突出模拟试验的研究历程进行阶段划分。研究表明:20世纪50—60年代,成功诱导了突出,初步考察诸因素对突出的影响;70—90年代,深入探究突出发生的力学判据及突出过程,并提出数十种有关突出机理方面的假说;21世纪初,以组建三维模拟试验台进行试验为特点,大大提高了模拟试验条件与现场的相似度,但在力学加载系统的稳定性和可调性、模型的整体密封性、测试探头的精度等方面仍需改进。

To take advantage of research results of laboratory coal and gas outburst simulation experiments at home and abroad,voluminous documents were widely referred to and the past research results were analyzed and summarized.Taking the progressive degree of coal and gas outburst experiment as the thread,the research course was divided.The three research stages are： In the first stage（fifties and sixties last century）,field similar outburst was successfully reappeared in the laboratory and the influences on the outburst from all kinds of factors,such as the gas pressure,the crustal stress,the coal strength,and so on,were studied;In the second stage（seventies,eighties and nineties last century）,the mechanical criterion and process of outburst were thoroughly studied and dozens of outburst mechanism hypothesises were proposed;The third stage（the turn of the century） was characterized by carrying on simulation experiment with 3-D apparatus.Although the simulation conditions were more close to the field,further improvement work should be done in stability and controllability of mechanical loading system,overall leak-proof quality of apparatus,precision of sensor,etc..
