基于集对理论的煤与瓦斯突出预测研究

 摘要：本文以集对理论为基础，结合相似数确定权重的方法，建立了煤与瓦斯突出预测模型。选取了钻屑量、瓦斯涌出初速度、解吸强度、电磁辐射强度和电磁辐射脉冲5种预测指标，运用相似权法确定了各预测指标的权重。利用该模型对掘进工作面突出危险性进行了预测，评价结果符合现场实际情况，表明该方法具有较强的可靠性和实用性，为煤与瓦斯突出预测提供一种新的方法，对煤矿的安全生产具有重要的指导意义。

Study on Prediction of Coal and Gas Outburst Base on Set Pair Theory

Base on the set pair theory,in combination with the similar figure set weight method,a prediction model of the coal and gas outburst was established.There were five predicted indexes selected as the drillings value,the gas initial emission speed,the desorption strength,the electromagnetic radiation strength and electromagnetic radiation pulse.The similar weight method was applied to determine the weight of each predicted index.The model was applied to predict the outburst danger of the gateway driving face.The evaluation results could meet the site actual conditions and showed the strong reliability and practicability of the method.Thus a new method could provide to the prediction of the coal and gas outburst and could have the important guidance to the mine safety production.
