Prediction method of coal spontaneous combustion based on relevance vector machine

Gong-kuang zidonghua, 2020
In terms of coal spontaneous combustion degree prediction, the radial basis function (RBF) neural network method is complex in structure and easy to fall into local optimum, the kernel function based on support vector machine (SVM) is sensitive to ...

Estimation of greenhouse gas emissions from spontaneous combustion/fire of coal in opencast mines – Indian context [PDF]

, 2016
There are a significant number of uncontrolled coal mine fires (primarily due to spontaneous combustion of coal), which are currently burning all over the world. These spontaneous combustion sources emit greenhouse gases (GHGs). A critical review reveals

Comparative analysis of coal and coal-shale intrinsic factors affecting spontaneous combustion

International Journal of Coal Science & Technology, 2018
Coal and coal-shales tend to undergo spontaneous combustion under favourable atmospheric conditions. Spontaneous combustion liability index and intrinsic properties of coals and coal-shales varies between (above and below) coal seams.
