摘要
为了提高瓦斯涌出预警技术的准确性,阐述了瓦斯涌出特征预警效果辨识方法,基于最优化理论建立了预警指标及其临界值的优选方法,并利用计算机选取流程,实现预警指标及其临界值的自动确定。该方法大幅缩短了预警指标及其临界值的考察时间,规范了预警指标确定方法,提高了瓦斯涌出预警技术的普适性。该方法在平舒煤业公司81111尾巷掘进工作面进行应用,实践效果较好。
In order to improve the accuracy of the gas outburst early warning technology, the recognition method of the characteristics of gas emission and its early warning effect was expounded in this paper, based on the optimization theory, the optimizing method for the early warning index and its critical value was established, and with the selection process of computers, the automatic determination of the early warning index and its critical value was realized. With this method, the inspection time for the early-warning index and its critical value was greatly shortened, the determination method for the early warning index was standardized, and the universality of the gas outburst early warning technology was thus improved. Better application effect of this method has been got in 81111 tailgate heading face in Pingshu Coal Mining Company.
