摘要:
通过分析新兴煤矿煤与瓦斯突出事故，发现在事故中由于煤与瓦斯突出事故诱发了激波的生成，瞬间产生的巨大超压，引起风流逆向，大量瓦斯随逆向风流从突出地点扩散传播至二水平，接触卸载巷电机车架空线所产生的电火花，从而引发瓦斯爆炸事故。提出了突出激波对事故的影响并分析了突出激波的形成及其破坏作用，研究了影响突出激波破坏作用的影响因素，得出参与突出的瓦斯量和瓦斯压力是影响激波强度的关键因素。有助于了解突出后的气流动力演化规律，并为煤与瓦斯突出事故的防灾、救灾措施的制定以及提高矿井的抗灾能力提供了参考。
Abstract:
In this paper the coal and gas outburst accident process of Xinxing coal mine was analyzed. The study showed that the coal and gas outburst accident induces the happen of shock wave, which introduces the enormous overpressure momentary, as well as the air flow reverse. The gas explosion caused by reverse air with a large number of gas flows to the second level of Xinxing coal mine and contact with spark generated by motor vehicles overhead lines in unload roadway. The impact of outburst shock wave in accident was proposed and the formation and destruction outburst shock wave were analyzed. The amount of outstanding gas and gas pressure was key factor affecting the strength of shock wave by studying the factors on damaging effects of shock wave hased on the coal and gas outburst accident of Xinxing coal mine. It not only helps to achieve an improvement for understanding of dynamic patterns during coal and gas outburst, but also provides reference for coal and gas outburst accident prevented, disaster relief measure constituted and the resilience improved of the coal mine.
