【摘要】 煤与瓦斯突出是发生在煤矿井下采掘过程中的一种极其复杂的瓦斯动力现象,是井下严重灾害之一,煤与瓦斯突出区域预测有着重要的意义。在大量总结前人研究成果的基础上,对川东褶皱带的形成、演化过程进行了详细阐述,并研究了川东地区煤矿煤与瓦斯突出灾害严重的原因。详细研究了华蓥山矿区地质构造对煤层瓦斯的控制规律和李子垭井田瓦斯赋存规律。在搞清瓦斯赋存规律的基础上,对瓦斯含量和构造煤分布进行了预测。研究了李子垭井田煤与瓦斯突出特征及影响因素,利用改进的模糊层次分析法对煤与瓦斯突出影响因素进行了分析,并利用C语言程序计算出了各影响因素权重大小,对计算结果进行了评价。在此基础上,划分了李子垭井田煤与瓦斯突出危险区、严重危险区和无突出危险区,提高了煤与瓦斯突出预测的准确性。更多还原

【Abstract】 Coal and gas outburst occurred in the process of excavating coal underground is an extremely complex phenomenon of gas dynamic,is one of the serious underground disasters. The regional forecast of coal and gas outburst has great significance.On the basis of previous studies, this article states the formation and evolution of Chuandong fold belt in detail and studies the reasons of serious coal and gas outburst in East Sichuan. This article also studies control rule of geological structure to the coal seam gas in Huayingshan mining area and gas storage rule in Liziya minefield. Based on the content of finding out the gas storage rule, this article predicts gas content and distribution of tectonic coal. This article studies about characteristics and influence factors of coal and gas outburst in Liziya minefield, analyzes influence factors of coal and gas outburst by use of enhanced fussy AHP and evaluates the calculation results. Liziya minefield was divided into coal and gas outburst dangerous area、serious dangerous area and safe area, the accuracy of the forecasts of gas disaster was improved.更多还原
