Forecasting Method of Coal and Gas Outburst Based on KPCA-SVM

Gong-kuang zidonghua, 2010
The paper proposed a forecasting method of coal and gas outburst based on KPCA-SVM. The method firstly used KPCA to select features of correlative indexes influencing coal and gas outburst, then used SVM to make classified forecasting coal and gas ...

Effect of Coal Particle Breakage on Gas Desorption Rate during Coal and Gas Outburst

Applied Sciences
The gas contained in coal plays a crucial role in triggering coal and gas outbursts. During an outburst, a large quantity of gas originally absorbed by coal is released from pulverized coal. The role this part of the gas plays in the process of coal and gas outbursts has not been clearly elucidated yet.

Study on influence of gas content of coal and gas outburst

IOP Conference Series: Materials Science and Engineering, 2017
In order to study the influence of gas content on the strength of coal and gas outburst, a set of device for simulating coal and gas outburst is improved by adding flowmeter and gas pressure sensors. The simulation experiments of coal and gas outburst were carried out with gas content of 7.5m3/t, 8.0m3/t, 8.5m3/t and 9.0m3/t respectively.
