煤与瓦斯突出区域预测技术的研究

Research of Forecast of Coal and Gas Outburst

煤与瓦斯突出是煤矿井下一种复杂的动力现象,它严重地威胁着煤矿的安全生产。区域预测是以突出机理为基础的一种预测。通过对煤与瓦斯突出理论的分析结合层次分析法、模糊综合评判等理论,分析确定了井田范围内影响煤与瓦斯突出的地质构造、地应力、煤质煤体结构、煤层瓦斯赋存条件和瓦斯参数等重要因素及相互关系,确定出煤与瓦斯突出预测综合指标进而完成突出危险的区域预测。

Coal and gas outbursts, a threat to the production safety, is a complex dynamic phenomenon. This paper, based on the coal and gas outbursts theory, fuzzy mathematics, analyzes the element of coal and gas outbursts include geological structure, stress, coal structure, conditions of gas occurrence and gas parameters etc.and determined the composite indicator of the forecast of the coaland gas outbursts.
