摘要
为提高煤与瓦斯突出预测的准确性和可靠性,提出利用正负靶心灰靶决策模型进行煤与瓦斯突出危险性评价的方法.根据选取的20组矿井的突出单项指标数据,定义正、负两个靶心并分别计算靶心距,通过目标权重优化模型得到各突出影响因素的权重,依据计算出的综合靶心距大小划分煤与瓦斯突出危险性等级,并利用建立的煤与瓦斯突出预测模型对选取的10组矿井进行突出危险性评价,评价结果与矿井实际情况一致.研究结果表明:利用正负靶心灰靶决策模型进行煤与瓦斯突出危险性评价是可行的.
In order to improve the accuracy and reliability of prediction of coal and gas outburst, a method based on grey target decision model with positive and negative clouts was put forward to predict the outburst of coal and gas. According to the data from the selected 20 measure stations of coal mine, the positive clout and the negative clout are defined, and the positive and negative target distances are calculated. Then, the weight of each influencing factor is obtained by the optimization model of the target weight. Finally, the comprehensive distance to target center is calculated, and the risk level of coal and gas outburst is divided. When using this model to evaluate the outburst hazard degree of 10 coal mines, the forecast result is consistent with the actual situation.Thus, the model is feasible in practice to assess the possible of coal and gas outburst.
