摘要
瓦斯突出相关影响因素具有明显的时空特性,煤层突出危险程度的判别是一个多因素决定的模糊事件,模糊Petri网在离散事件动态建模具有突出的优势。在分析瓦斯突出空间数据分布及模糊性应用基础上,对比分析基本Petri网和模糊Petri网的知识表示,结合瓦斯突出各因素空间分布的特点,扩展了模糊Petrie网的相关组件成分,建立基于模糊Petri网的瓦斯突出空间模型,使瓦斯突出影响因素在不同的空间位置通过空间模型表示出来,进一步描述了瓦斯突出空间位置动态转换,在实际预测中具有现实的意义和可操作性。
Relational influence factors of coal and gas outburst have obvious space-time character,distinguishing criticality of coal and gas outburst is a fuzzy event that is decided by multifactor,fuzzy Petri nets has much advantage in the course of modeling discrete event.Spatial data distributing and fuzzy application of coal and gas outburst are analyzed,and while knowledge expression based on the contrast and analysis of the basic Petri nets and fuzzy Petri nets spatial modeling of coal and gas outburst is built based on fuzzy Petri nets,influence factors of coal and gas outburst are expressed by spatial modeling in the spatial location and the dynamic transition of coal and gas is described about in spatial location,all this have practicality and operation under the forecast of coal and gas outburst.
